Long before anyone used the word “influencer”, brands paid familiar faces to vouch for their products. Today the same idea runs through blogs, video channels, live streams and short clips, and it has reached every sector, including tightly regulated ones such as online gambling, where operators like casino money moon must follow strict rules on who may promote them and how. Understanding how influencer marketing got here explains why trust, transparency and rules now matter as much as reach.
Shift 1: From celebrity endorsement to everyday creators
For most of the twentieth century, endorsement meant a famous athlete or actor appearing in a print ad or a television spot. The audience knew it was advertising, and the distance between the star and the viewer was part of the appeal. That model began to change when blogs, and later YouTube in 2005 and Instagram in 2010, gave ordinary people an audience of their own. Early platforms also lowered the cost of entry: a phone and a free account were enough to start, which is why niche communities, from gardening to gaming, could suddenly reach audiences around the world.
These early creators were not famous in the traditional sense, but they were relatable. Followers saw them cooking, travelling or testing products in the same way they would, and that closeness made recommendations feel like advice from a friend. Brands noticed that trust, not fame, was doing most of the work.
Shift 2: From follower counts to real engagement
In the beginning, the headline number was the follower count. It was easy to measure and easy to compare, but it was also easy to inflate, and purchased followers made some audiences look larger than they were. Marketers learned that a large audience that does not interact is worth far less than a smaller one that does.
That lesson pushed brands towards smaller creators, often called micro-influencers, who tend to have tighter communities and more conversation under each post. Today, campaign planning usually looks at a broader set of signals:
- Engagement rate, meaning how many people like, comment or share.
- Audience fit, which checks whether the followers match the product’s actual customers.
- Conversions, such as clicks, sign-ups or purchases linked to the creator.
- Brand safety, which reviews the creator’s past content and tone.
Together, these measures give a more honest picture than a single big number, even though no metric is perfect on its own, and they have changed how budgets are divided between a few large creators and many small ones.
Shift 3: From single posts to platforms and long partnerships
The channels themselves multiplied. Short video on TikTok, long-form video on YouTube, podcasts, newsletters and live streams all compete for attention, and creators often work across several of them. A campaign is no longer one photo with a caption, but a mix of formats designed for each audience. Short video in particular rewards frequent, informal posting, which pushed creators to publish more often and to follow trends quickly.
The business relationship matured as well. One-off paid posts gave way to ambassador programmes, affiliate links and long-term collaborations, where a creator becomes a regular voice for a brand. Many creators now run small media businesses with teams, contracts and their own product lines, which makes them closer to publishers than to traditional endorsers.
Shift 4: From loose rules to clear disclosure
As influence grew, so did scrutiny. Regulators in the United States, the United Kingdom and the European Union expect paid or gifted content to be clearly labelled, and the US Federal Trade Commission updated its endorsement guidance in 2023. Social platforms added their own tools, such as branded content labels, to make disclosure easier.
Rules are tighter still for sensitive categories such as alcohol, finance and gambling, where authorities limit promotions that could appeal to minors. In 2022, for example, Twitch tightened its policy on streams promoting unlicensed gambling sites. For anyone reading this kind of content, the practical lesson is simple: check whether a post is labelled as an ad, and remember that gambling services are for adults only.
What comes next
The next chapter is already visible in virtual and AI-generated personalities, in shopping built directly into video, and in audiences who reward openness over polish. What will stay constant is the trade-off at the heart of the model: reach is only valuable when the audience believes what it hears. If you create, buy or simply watch this kind of content, ask yourself one question before you trust a recommendation: is the partnership clearly disclosed, and does it genuinely fit the person making it? Asking it takes a few seconds, and it protects both your trust and your wallet.
