History lesson: Once upon a time, back when dinosaurs still roamed the earth before the dawn of the 21st Century, Yahoo! Search Marketing Solutions was called Overture. It actually started out as the GoTo search engine in 1998, and then rebranded itself and shifted its focus to being an advertising provider on other search engines. This was in the days before Google became the dominant search engine and evil overlord advertising provider that it is today.
Overture provided "sponsored listings" (also known as PPC advertisements) to Yahoo!, HotBot, AOL, and lots of other search engines. They also provided paid placement in AltaVista, which was among the first search engines. Before Yahoo! bought it out, Overture became the largest and arguably best of the pay-per-click advertising providers online at that time.
Then in 2003, Yahoo! bought out Overture for $1.6 Billion in stock and cash.
In March 2005, Overture officially rebranded as Yahoo Search Marketing.
