While the term affiliate marketing is associated with the internet as a source of most of the ads that you see online, the true history is somewhat shrouded in mystery and lost to time. But the practice of installing ads on commercial property representing a separate but relevant product or service is as old as the concept of capitalism itself. The method of advertising made it easy for a vendor to display the ads of a neighbor of friend in their shop, or even sell some of the most popular items on the sales floor, usually in exchange for a small part of the profits of the sale. This arrangement was lucrative and profitable for everyone involved, as the brand was being displayed in a new location and both merchants were able to profit by it. Customers benefited as well, as they could purchase many goods at the same location.

This tradition eventually led to the supermarkets of the modern day, where thousands of products co-exist in the aisles, each and every product the direct result of negotiation with a company representative over price and product as well as profit margin and retail price. By allowing markets to sell affiliated products, affiliate marketing helps everyone to successfully benefit from a free market society. In this free market society, the supermarket is free to negotiate with whomever they choose for the freshest vegetables and products, as well as the cheapest prices and highest volume of production available to the supplier.

Once these systems of outsourcing and affiliate marketing were established, all manner of deals and arrangements were made to take advantage of the concept of affiliate marketing, resulting in the rampant use of affiliate marketing as it exists today on the modern day internet. As the use of affiliate marketing and cross branding become more and more commonplace, the options available to shoppers will become more and more diverse over time, leading to massive retailers like Wal Mart enjoying the lion's share of available business while mom and pop stores and other small businesses are left to struggle. The individual suppliers will continue to benefit greatly from the affiliate marketing arrangement, as some other entity conducts the sales while the sponsor simply collects the profits.

On the internet, affiliate marketing accounts for the majority of the advertising on the web. Ads are in constant rotation all over the internet, a subtle reminder of the cross branding and cross promotion of the products and services that together define the web and the business model that exists for affiliates to take advantage of. A ready system, designed to deliver the marketer's message to the untold millions on the web as well as stand in stark testimony to the power of affiliate marketing on the internet. This power of affiliate marketing, the ability to offer a product on another, relevant site without the need for complex middleware or roundabout methods of collecting purchase payment is critical the success of the web.

The simple point and click nature of the web makes this type of revolutionary business model possible, thanks to the multitude of web users and the instantaneous nature of internet communications.
