History Of Pay Per Click

In February 1998 Jeffrey Brewer of Goto.com, a 25-employee startup company (later Overture, now part of Yahoo!), presented a pay per click search engine proof-of-concept to the TED8 conference in California.[6] This presentation and the events that followed created the PPC advertising system. Credit for the concept of the PPC model is generally given to Idealab and Goto.com founder, Bill Gross.

Google started search engine advertising in December 1999. It was not until October 2000 before the AdWords system was introduced, allowing advertisers to create text ads for placement on the Google search engine. However, PPC was only introduced in 2002; until then, advertisements were charged at cost-per-thousand impressions. Yahoo! advertisements have always been PPC-based since their introduction in 1998.
