The frequency and method of payment vary as well. Most programs pay their affiliates monthly, although a few pay more frequently. Some require that affiliate earnings reach a specific threshold, which can be as low as $25 or as high as $100. Some programs don't have a threshold. There are programs that pay through direct deposit into your bank, but a vast number pay through PayPal.
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.
