The Evolution of Affiliate Marketing

Affiliate marketing has come a long way since its inception in the late 1980s. The concept began with William J. Tobin, who launched the first affiliate marketing program for his company, PC Flowers & Gifts, in 1989. By 1996, Amazon had launched its own affiliate program, Amazon Associates, setting the standard for the industry.

Over the decades, affiliate marketing has evolved alongside the internet. From the early days of e-commerce in the 1990s to the rise of social media and influencers in the 2010s, affiliate marketing has grown into a multi-billion dollar industry, with over $12 billion in annual global revenue.

In 2025, affiliate marketing continues to thrive, driven by advancements in digital marketing strategies, the increasing popularity of content creators, and a growing demand for online shopping. As the landscape evolves, so do the opportunities for affiliate marketers to innovate and succeed.
