The influencer marketing industry is on track to be worth up to $15 billion by 2022

 An Internet celebrity (also known as a social media influencer) is a celebrity who has acquired or developed their fame and notability through the Internet. The rise of social media has helped people increase their outreach to a global audience. Influencers can also be typical individuals rather than celebrities, who post their interest and sponsorships with brands. Today the most popular influencers are found on popular platforms like Instagram, YouTube, Snapchat, and TikTok. Within the last decade, studies show that Instagram holds a majority of the influencer population. Sometimes, influencers are known as 'Instagrammers'. Internet celebrities may be recruited by companies for influencer marketing to advertise products to their fans and followers on their platforms. Internet celebrities often function as lifestyle gurus who promote a particular lifestyle or attitude. In this role, they are crucial influencers or multipliers for trends in genres including fashion, beauty, technology, video games, politics, music, sports and entertainment.

The attractiveness of celebrities to everyday society creates that trust and confidence in which consumers translate into the credibility of the products being promoted. A 2001 study from Rutgers University had found that people were using "internet forums as influential sources of consumer information". This study suggested that consumers were using Internet forums and social media to make purchasing decisions over traditional advertising and print sources. The more personable an influencer is with their audience by engaging with them, the more encouraging they would be to purchase a product.

Companies nowadays are more concerned with feedback and comments they receive from their social media platforms, because consumers believe other consumers. Many rely on reviews to convince them to buy something. One bad review can cost a business a lot of revenue. A typical method of marketing between the influencer and the audience is "B2C marketing". B2C marketing, meaning Business to Consumer marketing, entails the strategies in which a business would undertake in order to promote themselves and their services directly to their target audiences. This is typically through the advertising and creating content through the influencer themselves. The intention is that their followers who relate or look up to certain influencers will be more inclined to purchase an item because their favorite 'Internet celebrity' recommended it. Internet celebrities typically promote a lifestyle of beauty and luxury fashion and foster consumer–brand relationships, while selling their own lines of merchandise. 

The early 2000s saw corporate attempts to use the Internet for influencing where some companies engaged with forums for promotion or to offer bloggers free products in exchange for positive reviews. Some of these practices were considered unethical.

The Blogstar Network, launched in 2004 by Ted Murphy of MindComet, invited bloggers to an email list to receive paid offers from corporations based on the type of posts they made. An example of this includes being paid a few dollars for reviewing a fast-food meal in their blog.

Blogstar is considered the first influencer marketing network. Murphy followed Blogstar with PayPerPost, launched in 2006, which paid influential posters at the larger forum and social media sides for each post about a corporate product. The payment rates were based on the influencer status of the individual. The very popular, PayPerPost, received a great deal of criticism as these influencers were not required to disclose their involvement with PayPerPost as traditional journalism would have, and made the public aware that there was a drive by corporate interests to influence what some people were posting to these sites. This site encouraged other companies to begin to create similar programs. Despite concerns, influencing marketing networks continued to grow through the rest of the 2000s and into the 2010s. The influencer marketing industry is on track to be worth up to $15 billion by 2022, up from as much as $8 billion in 2019, according to Business Insider Intelligence estimates, based on Mediakix data.

An article written by David Rowles titled: 'Digital Branding: A Complete Step-By-Step Guide to Strategy, Tactics, Tools and Measurements,' details as to how and what techniques these internet celebrities use to get more recognition on their platforms from users and brands. "Digital branding is the sum of experiences that we have online and it relies on the provision of value." It suggests that users are already exposed to the lives of their influencers as loyal fans, its easy for them to market companies as their fans feel as though they know the celebrities they follow, when the reality differs.

Self-branding

Self-branding, also known as personal branding, describes the development of a public image for commercial gain or social or cultural capital. The rise of social media has been exploited by individuals seeking personal fame and product sales. Platforms such as Instagram, Snapchat, VSCO, TikTok, and YouTube are the most common social media outlets on which online influencers attempt to build a following. Fame can be attained through different avenues and media forms, including art, humor, modeling, and podcasts. Marketing experts have concluded that "[people no longer] need to be familiar with complex coding languages or other technicalities to build websites because virtually anyone can upload text, pictures, and video instantly to a site from a personal computer or phone. With technological barriers crumbling, the web has become the perfect platform for personal branding
