"OneSearch" is completely new to me. I know Yahoo has a decent market in Asia, Japan I believe. I'm always surprised to see AOL mentioned in any context outside of history anymore.

Lots of people tricked through browser toolbars and self-installing "configuration CDs" i guess

I see those on computers run buy laymen who somehow installed one of those nasty toolbars that change the default search to Yahoo or other stuff.

Some of their success can be explained by the tyranny of the default. Some browsers use these search engine by default in some regions, and people don’t tend to change the defaults. I don’t know for sure, but I’d be surprised if Verizon don’t set it as the default on at least some of the devices they sell. Didn’t they recently announce Yahoo! Mobile as a cellphone service too?
