Nate writes "Overture announced that they bought AltaVista today for $140M in cash and stock. This follows closely on the heels of Yahoo's purchase of Inktomi. Considering the significant financial muscle of Yahoo and Overture, I hope that Google can continue to maintain their lead. For those of you who aren't familiar with Overture, they are the 800-pound gorilla in the pay-for-placement listing market. When you search in Yahoo, those Sponsor Matches at the top are provided by Overture."
