What began as a simple referral concept has grown into one of the most performance-driven, scalable channels in digital marketing. Understanding the history of affiliate marketing helps explain why it works so well today.
At Advertise Purple, becoming a leading affiliate marketing agency didn’t happen overnight. It took years of iteration, deep industry knowledge, and respect for the foundations laid by the pioneers who came before us. Getting to where we are today means understanding where this channel came from.
Affiliate marketing may feel like a product of the internet age. However, its roots go back further than most people realise. Referral-based selling is where someone earns a reward for directing a new customer to a business. It has existed in commerce for decades; the internet simply gave it scale, speed, and global reach.
The History of Affiliate Marketing: Key Milestones That Shaped the Industry
The Internet Changes Everything
The internet didn’t invent affiliate marketing, but it fundamentally transformed it. Before the web, referral programs were geographically limited. A local business could reward loyal customers for word-of-mouth recommendations, but the reach was always finite.
Once the internet arrived, those limitations disappeared. Entrepreneurs with limited resources could suddenly reach buyers anywhere in the world. E-commerce created entirely new revenue streams. The ability to track, measure, and optimise referrals in real time made affiliate marketing an attractive proposition for businesses of all sizes.
Amazon’s rise as the world’s most valuable e-commerce company is a testament to what the internet has unlocked. It also set the stage for affiliate marketing to become a mainstream growth channel.
1989: The Patent That Started It All
William J. Tobin filed for the patent of what we now recognise as affiliate marketing in 1989, establishing the first formal affiliate program for his company, PC Flowers & Gifts. An Army veteran with multiple entrepreneurial endeavours under his belt, Tobin became a genuine pioneer. He paved the way for countless businesses to adopt performance-based partnership models.
His vision was ahead of its time. The idea of rewarding third parties for driving sales was simple in principle, but the implications were enormous. The affiliate marketing industry, as we know it, traces its origins directly back to this moment.
1996: Amazon Opens Affiliate Marketing to the Public
Amazon took the concept Tobin had patented and made it accessible to everyone. Launched in 1996, the Amazon Associates Program allowed website owners to place product links and earn a commission on referred sales. It was the first affiliate program available to the general public at scale.
The Associates Program still operates today. Amazon recognised early that affiliate marketing was an efficient, low-risk way to acquire new customers and grow revenue. Publishers earned, Amazon grew, and a template was established that the entire industry would follow.
1994: Cookies and the Birth of Tracking Technology
Lou Montulli, a 24-year-old programmer, invented cookies in 1994. A cookie is a small data file stored on a user’s browser when visiting a website, and its implications for affiliate marketing were enormous.
Cookies made it possible to accurately attribute sales to specific affiliates. Tracking clicks, attributing conversions, and paying commissions fairly all became feasible at scale. Companies like Google and Microsoft later expanded on this foundation, creating the analytical and targeting infrastructure that underpins digital marketing today.
1998: The First Affiliate Networks Emerge
Commission Junction and Rakuten (both of which we work with at Advertise Purple today) became the first dedicated affiliate networks in 1998. These platforms opened doors for smaller businesses that wanted to launch affiliate programs without the infrastructure of a company like Amazon.
Networks created a standardised environment where advertisers and publishers could connect, track performance, and manage payments. This was the groundwork that made scaling an affiliate strategy possible for businesses of every size.
2000 to Today: The Same Principles, Greater Scale
The core mechanics of affiliate marketing have remained consistent. What has changed is the scale, the technology, and the sophistication of the players involved. New networks have emerged, tracking capabilities have advanced significantly, and the pool of affiliates has grown to hundreds of thousands globally.
Advertise Purple was founded by Kyle Mitnick in 2009, with the conviction that properly and patiently managed affiliate management would produce outstanding results. That philosophy hasn’t changed. Patience, precision, and strong affiliate relationships remain at the heart of what we do for every client we take on.
Our work as a UGC marketing agency also highlights how the affiliate model has changed. Authentic creator content now plays a central role in driving affiliate conversions across every major vertical.
