Major Search Engines :)   

Google was originally a Stanford University project by students Larry Page and Sergey Brin called BackRub. By 1998, the name had been changed to Google, and the project jumped off campus and became the private company Google. It remains privately held today.

Launched in 1994, Yahoo is the web's oldest "directory," a place where human editors organize web sites into categories. However, in October 2002, Yahoo made a giant shift to crawler-based listings for its main results. These came from Google until February 2004. Now, Yahoo uses its own search technology

MSN Search is definitely one to watch. The service was previously powered by LookSmart results and gained top marks for having its own team of editors that monitored the most popular searches being performed to hand-pick sites believed to be the most relevant. The system worked well.
