Evolution of Influencer Marketing

What is influencer marketing?

Somewhere along the line of social media’s infant chronology, people realized that the posts they listed online actually carried weight with other social media users. And so, the influencer was born.

Influencer marketing, in its purest form, is a type of social media marketing that uses endorsements from influencers. Influencers are viewed as experts within their niche and have a community of other people who follow them, listen to their advice, and are generally influenced by their content.

Influencer marketing works because of the number of people who trust online creators and the products they promote across their channels. Research from Matter Communications found that 69% of consumers trust information from influencers, friends and family more than information coming directly from a brand. Separately, Sprout Social reported that 86% of consumers make at least one purchase inspired by an influencer each year.

That trust is the entire asset. Everything else in this article is a story about brands, platforms and agencies learning how not to break it.

Influencer marketing timeline: 1890s to 2026

Influencer marketing is far older than social media. What social media changed was the scale, the speed, and who gets to do it.

 What happened

• 1890s: Royals and stage celebrities are paid to endorse consumer goods. Queen Victoria’s endorsement of Cadbury’s cocoa is among the earliest documented brand-celebrity partnerships.
• 1930s to 1950s: Radio and television turn endorsement into mass media. Brand mascots and celebrity spokespeople become standard practice.
• 2005 to 2009: YouTube launches. The first generation of native internet personalities emerges. Blogging and “mommy blogger” outreach become the first recognisable form of digital influencer marketing.
• 2010: Instagram launches. Visual-first content makes lifestyle endorsement frictionless.
• 2013 to 2016: Vine popularises short-form video and compresses the path from unknown to famous into 24 hours. It shuts down in 2016 after failing to monetise its creators.
• 2016 to 2019: TikTok inherits the short-form formula. Influencer marketing becomes a line item rather than an experiment. The industry is worth roughly $1.7 billion in 2015.
• 2020 to 2022: Lockdowns collapse the distance between creator and consumer. Budgets shift from production to creators. Social commerce infrastructure starts to arrive.
• 2023: The FTC issues the biggest revision to its Endorsement Guides in over a decade, extending disclosure obligations to virtual and AI-generated endorsers.
• 2024 to 2025: Measurement scrutiny intensifies. Brands consolidate creator programmes. The market reaches an estimated $32.55 billion in 2025, per Influencer Marketing Hub.
• 2026: Market estimated at $40.51 billion. Nano and micro influencers take nearly half of US creator spend. Creator content moves into retail media, connected TV and in-store.

When did influencer marketing start?

If you mean paid endorsement, the 1890s. If you mean influencer marketing as we practise it now, with independent creators, audience-native content, and performance measurement, the honest answer is around 2010 to 2013, when Instagram and Vine gave ordinary people distribution that used to require a broadcaster.

The rise of influencer marketing in the digital age

Influencers were never part of a broader plan for the future of marketing. They came about by circumstance, out of the once-minor fact that other people online valued the content they were posting.

YouTube has long been a nurturer of popular personalities. Before the MrBeasts and the Jake Pauls were Ray William Johnson, Smosh, Ryan Higa, Zoella and Jaclyn Hill, to name a few.

Despite its success at drawing large audiences, YouTube in the early 2010s had not quite figured out creator monetization. When Vine launched in 2013, its format of shorter videos got the ball rolling on short-form content. Vine required less work per post, whereas YouTube needed longer videos and lower output. More significantly, shorter videos meant a higher demand for content. Higher demand meant an influx of content creators. Vine turned the casual videographer into a hero creator within 24 hours. Much of that effectiveness was baked into the format itself: short clips made content easy to discover, quick to land a joke, culturally fluent, and simple to consume in bulk. Those same qualities are exactly what make the short-form platforms we leverage today so effective. 

For all of Vine’s qualities, the app failed to invest in its creators, forcing it to shut down in 2016. The platform’s top creators were cast across Instagram, YouTube and Facebook. Out of Vine’s death came the conditions for TikTok‘s true birth: Musical.ly, the lip-syncing app that ByteDance acquired and later transitioned into TikTok. It was on Musical.ly that some of today’s biggest US creators, like Loren Gray and Baby Ariel, first built their audiences, adopting the same short-form formula that had driven Vine’s success years earlier. 

Influencer marketing takes off

The mid-2010s are when influencer marketing really started taking off. Brands began to realize the potential of online creators, who were now being paid handsomely for sponsorships and endorsements.

Ten years on, it is not a tactic on the edge of the plan. It is the plan. Roughly 86% of US marketers used influencer marketing in 2025, up from 64.5% in 2020, according to eMarketer, and the Influencer Marketing Hub Benchmark Report 2026 found that 87.49% of brands expect their influencer budgets to increase, with 72.22% planning increases of 50% or more.

How influencer marketing has evolved

Consumer habits keep moving, so marketers keep adapting. Three shifts define the last decade.

From reach to relevance

Influencer marketing a few years ago still followed the logic of partnering with the biggest names available, as if the more followers a creator had, the better the result. That has been comprehensively disproved. Micro and nano creators, ranging from around 1,000 to the hundreds of thousands of followers, have a more personal connection with their audience and stronger engagement rates.

This is no longer a point of view; it is where the money now goes. eMarketer data presented at its Creator Trends 2026 Summit shows nano and micro-influencers account for 49.9% of US creator spend, up from less than a fifth a few years ago. 

Our own campaign data backs this up. IBEX, Goat’s proprietary technology, shows micro-influencers regularly pulling engagement rates up to 60% higher than macro-influencers, and we’re seeing brands act on that: spend across micro and nano tiers has grown nearly fivefold in the last two quarters alone, with their share of total budget more than tripling from 2.5% to 8.9%, even as high and mid-tier spend has been cut by over half. Brands have increasingly recognised the benefits of activating smaller influencers on long-term partnerships. It is more cost-effective, and a longer activation produces more quality content, engagement and results.

The shift back to long-form, slow content

Like most things in this industry, the trend cycle repeats. Having chased short-form for the best part of a decade, brands and creators alike are now seeking a deliberate mix of short and long-form content. Long-form YouTube is being used again for in-depth video essays and explainers that nurture a community over time rather than chasing a single view spike, while Substack is giving creators a home for richer, more substantial writing than a caption ever could. We unpacked this shift in more detail at our US event, Desperately Seeking Substance; the key takeouts are worth a read for anyone building a longer-term content strategy.

The rise of paywalled content

Alongside that shift, creators are increasingly building paid communities on top of their free, public-facing presence. Substack and Patreon are the clearest examples, but the same logic is showing up inside platforms like TikTok too, where creators with highly engaged audiences offer additional paid content for fans who want more than the free feed provides. For brands, this opens up a new kind of freemium space to activate within, reaching audiences who have already shown they are willing to pay for deeper access to a creator they trust.

From advertisement to authenticity

Today’s consumer is highly receptive to whether an ad is genuine, a shift that can be linked to the expectations of Gen Z consumers. The days of influencers pushing followers to buy a product simply because they have been paid to do so are gone. Brands have instead identified more unique and engaging ways to activate influencers, often around an initiative or a reactive cultural moment.

From external to embedded 

The definition of “influencer” has widened considerably. Employees, founders, subject matter experts and customers all now function as creators. See our work on employee-generated content and the top B2B influencers for how far that has travelled from the lifestyle-creator model the industry started with.

How have influencers transformed modern marketing?

Influencer marketing has enabled brands to reach much more targeted audiences online. Endorsements and product placements have evolved into an opportunity for brands to tap into entire communities.

An influencer’s audience is highly engaged and has learned to trust that influencer’s recommendations. That is a significant shortcut for brands who would otherwise have to spend years cultivating an audience of their own.

More fundamentally, influencer marketing has changed what audiences expect. Credibility, trust and authenticity are now baseline requirements rather than differentiators. It also leverages what social media users already like about their respective platforms, which is why influencer content is something users actively seek out.

How influencer marketing agencies have evolved

The creators changed. So did everyone servicing them. The agency model has been through four fairly distinct phases.

Phase one: the booking desk (roughly 2010 to 2015)

Early influencer agencies were essentially talent brokers. The value was the contact list. Brands could not find creators, so agencies found them, negotiated a fee, and got a post live. Campaigns were measured in impressions because impressions were the only thing anyone could measure.

Phase two: campaign execution (2015 to 2019)

As budgets grew, so did the scope of what agencies could offer. Briefing, contracting, content approvals, usage rights, disclosure compliance and reporting all became part of the agency’s remit. The value moved from who you knew to whether you could run fifty creators at once and deliver flawlessly.

Phase three: always-on programmes (2019 to 2023)

One-off campaigns gave way to long-term partnerships and ambassador structures. Agencies started building creator communities for brands rather than renting audiences a post at a time. Paid amplification of creator content became standard, and influencer teams expanded into media buying to match.

Phase four: performance and commerce (2023 to now)

This is where most of the industry currently sits. Creator content is judged against the same standards as any other acquisition channel. Influencer agencies are expected to prove incrementality, tie activity to sales, and operate inside social commerce environments. Our own work on influencer commerce is a direct response to that shift.

The trend running underneath all of this is in-housing. The Influencer Marketing Hub Benchmark Report 2026 found that 66.33% of brands now run their influencer programmes fully in-house, and that rising creator costs are the single biggest challenge marketers report, at 35.4%.

That combination is the defining commercial question for agencies. If a brand can run the mechanics itself, and its costs are climbing, the agency needs to bring something the mechanics alone can’t.

Influencer marketing in 2026: the numbers that matter

For the full picture, see our influencer marketing statistics page. These are the figures that specifically illustrate how far the industry has travelled.

• The market is worth an estimated $40.51 billion in 2026- up from $31.07 billion in 2025 and forecast to reach $152.56 billion by 2031, a CAGR of 30.36%, per Mordor Intelligence. Set against roughly $1.7 billion in 2015, that is a twenty-fold expansion in around a decade.
• Brands make an average of $5.78 for every $1 spent – Top-performing campaigns return $18 to $20 per dollar, according to the Influencer Marketing Hub Benchmark Report 2026.
• 87.49% of brands expect budget increases, and 72.22% expect increases of 50% or more- from the same 600-plus respondent benchmark survey.
• US social media creator revenue will reach $21.10 billion in 2026, more than doubling since 2022, per eMarketer’s February 2026 forecast. The IAB’s Creator Economy Ad Spend and Strategy Report puts total US creator ad spend, including paid amplification, at $37 billion in 2025, up 26% year on year and growing roughly four times faster than the broader media industry, with around $43.9 billion forecast for 2026.
• Nano and micro creators take 49.9% of US creator spend- up from less than a fifth a few years ago (eMarketer).
• Creators earn 59% of their revenue from sponsored content in 2026, followed by platform payouts at 24.4% and affiliate marketing at 8.2%, according to eMarketer’s creator economy analysis.
• TikTok Shop is forecast to reach $23.41 billion in US ecommerce sales in 2026- a 48% year-on-year increase, while US livestreaming retail ecommerce is projected to rise 35% to $19.76 billion (eMarketer).
• 69% of consumers trust influencer recommendations over direct brand messaging, and 86% make an influencer-inspired purchase at least once a year (Sprout Social).
• The wider creator economy was valued at around $250 billion in 2023 and projected to approach $480 billion by 2027, according to Goldman Sachs.
• Influencer fraud is estimated to waste $4.8 billion globally in 2026– (Sumsub), a reminder that scale has brought its own failure modes.

How influencer marketing changed between 2024 and 2026

We wrote an earlier version of this article in 2024. Six shifts have happened since. For what is landing right now, see our influencer marketing trends for 2026.

1. Long-term partnerships became the default, not the differentiator

 In 2024, committing to a creator for a year was a point of view. In 2026, it is table stakes, and the interesting question has moved on to how you structure creator rosters, tiering and exclusivity across a category.

2. Micro and nano won the budget argument outright

The case for smaller creators used to rest on engagement rate. It now rests on where nearly half of US creator spend actually goes.

3. Social commerce stopped being a prediction

In 2024 we wrote that TikTok Shop was “ramping up its efforts in the West”. It is now forecast to do $23.41 billion in US ecommerce sales in a single year.

4. AI moved from a prediction to plumbing

Only 10.56% of marketers report no AI use in their influencer programmes at all. But adoption is uneven in a telling way: AI handles creator discovery for 36.67% of teams and fraud detection for just 7.22%. Brands trust AI to find creators, not to verify them. Our piece on AI influencers covers the synthetic creator side of this.

5. Creator content left social

Brands are now placing creator-made assets in retail media networks, connected TV and in-store environments. The content format outlived the channel it was invented for.

6. Deinfluencing matured into scepticism as a baseline

The 2023 deinfluencing ‘trend’ transformed into a philosophy, a permanent recalibration of how audiences read sponsored content, and it is why disclosure and genuine product fit now matter commercially, not just legally.

How regulation shaped influencer marketing

For most of its first decade, influencer marketing operated in a regulatory vacuum. That vacuum closed, and the rules have shaped the practice as much as any platform change.

The FTC 

The Federal Trade Commission’s Endorsement Guides, codified at 16 CFR Part 255, require disclosure of any material connection between a brand and an endorser. The 2023 revision was the biggest in over a decade. It tightened the clear-and-conspicuous standard, brought platforms and review sites into scope, added explicit prohibitions on creating, buying or suppressing consumer reviews, and extended disclosure obligations to virtual and AI-generated endorsers. The FTC’s own Disclosures 101 for Social Media Influencers remains the clearest baseline reference for creators and brand teams.

Material connection is broader than most brands assume. Gifted product creates one. So does an affiliate commission. So, in the FTC’s framing, can amplification behaviour such as tagging or reposting.

The UK

In the UK, the ASA and CMA impose closely aligned transparency requirements on influencer advertising: commercial content must be clearly identifiable as an ad. ASA monitoring has repeatedly found substantial non-compliance; in its 2024 review, approximately 57% of influencer content identified as advertising was adequately disclosed. 

AI disclosure

This is the live edge. The EU AI Act’s Article 50 transparency obligations apply from 2 August 2026. In the US there is no standalone federal AI disclosure statute, so existing FTC deception and endorsement law does the work, but state legislation is arriving: New York’s Synthetic Performer Disclosure Law, A.8887-B/S.8420-A, took effect on June 9, 2026. It requires advertisers to make a clear and conspicuous disclosure when an advertisement features an AI-generated “synthetic performer,” with civil penalties of $1,000 for a first violation and $5,000 for subsequent violations. 

The practical implication for brands running cross-border programmes is that a campaign compliant in one market may not be in another, and that compliance now needs to be designed into briefs rather than checked afterwards.

Predictions for the future evolution of influencer marketing

Synthetic creators enter the mix

Virtual influencers have become a hot topic, with industries like beauty and fashion leading the adoption. However, audiences are increasingly cynical of AI and are becoming sharper at spotting it. The brands winning trust right now are leaning into real creators and real perspectives. As AI adoption in advertising continues to be even more deeply ingrained in audiences’ experiences, human-made and approved content will become a much scarcer, more valuable asset, not a less relevant one.

Measurement converges with the rest of the media mix

Influencer marketing has spent a decade being measured on its own terms. It is now being folded into the same incrementality and MMM frameworks as everything else, which is a promotion disguised as a burden.

Creator content becomes a format rather than a channel

Creator-made assets are already running in CTV, retail media and in-store. “Influencer marketing” no longer describes where content appears; it describes how it is made and who makes it. 

Trust becomes the constraint on growth

With $4.8 billion lost to influencer fraud and a rising volume of synthetic profiles, verification is likely to be the growth bottleneck rather than budget. Notably, it is the part of the workflow where AI adoption is lowest.

How brands can stay ahead of the trends

Brands looking to diversify their marketing through influencers should make a conscious effort to stay in the loop.

The most immediate way is to consume creator content directly. If there are new developments in the industry, creators are the first to know, since it is their playground. Keeping an eye on industry leaders, competitors, and outlets within your niche is the other half of it.

Beyond that: build a benchmark sheet of eight to ten metrics that map to your actual goals, and set targets against your own historical performance rather than borrowed industry averages from a different category and audience.

Then and now: influencer marketing campaigns that show the shift

The clearest way to see the evolution is to put a campaign from the old model next to one from the current one.

Then: Audi

Audi approached Goat to increase awareness, desirability and test drive numbers for its Q range SUVs. We devised a creative brief in which influencers shared a unique passion point or aspect of their life, and aligned it organically with their model of choice. That ranged from cooking and parenthood to entrepreneurship and snowboarding.

Nine influencers created content across Instagram posts, Stories and IGTV, showing how the car fitted into their lifestyle in a way that felt natural to their audiences. We combined the organic content with a targeted paid social strategy, with a clear call to action driving click-through to Audi’s virtual assistant messenger to arrange test drives.

The campaign drove 8.3 million impressions, 39,000 clicks and 536 customer referrals.

Then: Arm & Hammer

We were tasked with delivering a full-funnel influencer campaign for Arm & Hammer’s laundry detergent sheets, targeted at parents across the US. The brief called for results at every stage of the funnel, not just awareness.

We combined organic and paid influencer content with an industry-first Amazon Ads solution, developed in partnership with Amazon, that let us push influencer content directly into Amazon’s ad suite while keeping the native look of a social post. Using IBEX, we selected nine creators who could speak authentically to the product, from a mum of four sharing cleaning tips to a family account built around comedic everyday moments, then repurposed their organic content for paid media and retargeted audiences who had already seen it on social with lower-funnel messaging that clicked through to the Amazon product page.

The campaign delivered 96 million impressions, 194,000 clicks and $300,000 in attributable sales, a 1.71 ROAS against an industry benchmark of $0.65, while beating its own KPIs for impressions and clicks by 36% and 137% respectively.

Both campaigns worked. But note what they have in common: nine creators combining organic content with paid social amplification, and success measured not by reach but by a clear commercial action, test drives requested, product sales made. 

Now

Contemporary programmes look structurally different. They run continuously rather than in flights, weigh heavily toward micro and nano creators, and are measured against commercial outcomes rather than impressions.

Two current examples of that model:

• Our appointment as SoundCloud’s US influencer agency of record, an always-on remit rather than a campaign brief.
• Our FMCG Influencer Marketing Report, which breaks down how brands including Poppi, Tide, Quaker Oats and CeraVe are building stories, connection and prestige through creators.

Why brands invest in influencer marketing in 2026

Influencer marketing drives growth across the entire purchase funnel, through authentic, hyper-engaged content that usually runs multichannel.

The commercial case is no longer speculative. An average return of $5.78 per $1 spent, 87.49% of brands planning budget increases, and 86% of US marketers already using the channel add up to something that has stopped being a test and started being infrastructure. (Source)

What has changed is the standard of proof. In 2018, you could win the argument internally with an engagement rate. In 2026, you need a measurement design that survives scrutiny, a creator roster that matches the category, and a compliance process that holds up in three jurisdictions.

That is the actual evolution. Not that influencer marketing got bigger, but that it got held to the same standard as everything else, and passed.

Influencer marketing FAQs

When did influencer marketing start?

Paid endorsement dates to the 1890s, when royals and stage celebrities were paid to promote consumer goods. Influencer marketing in its modern form began around 2010 to 2013, when Instagram and Vine gave independent creators the kind of distribution that had previously required a broadcaster or publisher.

Who was the first influencer?

There is no single answer, but the earliest documented brand-celebrity partnerships date to the late 1800s. In the digital era, the first generation of YouTube personalities from 2005 onward, and the earliest bloggers receiving product for review, are the closest thing to a starting point for the model we use today.

Who was the first social media influencer?

As for the first social media influencer specifically, that title is even more contested. MySpace, launched in 2003, is often cited as the first platform where ordinary users built the kind of personal following brands would later pay to reach, and commentators have pointed to figures like Julia Allison, an early blogger and media personality active across multiple platforms in the mid-2000s, as one of the first people to operate as an influencer before the term existed. But as with the origin of influencer marketing itself, there’s no single agreed-upon answer. 

How has influencer marketing changed?

Three main ways. Budget has shifted from mega-creators to micro and nano creators, who now take 49.9% of US creator spend. Measurement has shifted from impressions to commercial outcomes. And regulation has shifted from nonexistent to a genuine operational requirement across the US, UK and EU.

How big is the influencer marketing industry in 2026?

An estimated $40.51 billion globally in 2026, up from $31.07 billion in 2025, according to Mordor Intelligence. The wider creator economy, including subscriptions and merchandise, was valued at around $250 billion in 2023 by Goldman Sachs and projected to approach $480 billion by 2027.

What is the future of influencer marketing agencies?

Agencies are moving toward four areas that are harder to replicate in-house: peak-capacity scale, proprietary cross-category data, measurement design that withstands financial scrutiny, and cross-border regulatory compliance. With 66.33% of brands now running programmes in-house, the agencies that thrive will be the ones offering something a brand structurally cannot build for itself.

Why is influencer marketing so powerful?

It leverages creators who have spent time cultivating an audience, gaining their trust and perfecting their craft. That lets brands reach targeted audiences authentically, building credibility and maximizing ROI, rather than spending years building an owned audience from scratch.

What are the best platforms for influencer marketing?

Influencer marketing performs strongest across YouTube, Instagram, TikTok, Twitch and Pinterest. Creators can also be activated across Facebook, LinkedIn and X, with LinkedIn now central to B2B influencer marketing.

Can The Goat Agency help with influencer marketing?

Yes. The Goat Agency was born from influencer marketing and has been developing global, award-winning influencer campaigns since 2015.
