Online advertising started to take shape – Cost Per Mille (CPM) models and paid placements were important components of the marketing mix, but difficult to measure. An emphasis on quality traffic and conversion helped transition marketers from buying impressions and site visitors, to paying exclusively for traffic that resulted in a sale and affiliate marketing lead the charge.
The concept of affiliate marketing on the Internet was conceived of, put into practice and patented by William J. Tobin, the founder of PC Flowers & Gifts. Launched on the Prodigy Network in 1989, PC Flowers & Gifts remained on the service until 1996. By 1993, PC Flowers & Gifts generated sales in excess of $6 million per year on the Prodigy service. In 1998, PC Flowers and Gifts developed the business model of paying a commission on sales to the Prodigy Network.
