Yahoo and Microsoft have each launched mobile search and advertising initiatives this week. Yahoo has introduced display advertising on its mobile-specific Web sites in 19 countries in the Americas, Europe and Asia. It also released a new version of its downloadable mobile client, Yahoo! Go 2.0. The new "gamma" version features the ability for consumers to search directly from maps and share oneSearch results, news articles and the service directly with friends. Zach Rodgers has the details at ClickZ News.
Microsoft launched Live Search for Mobile at the 3GSM World Congress in Barcelona, releasing v 1.0 of its client application for Windows Mobile devices. Features include category-based local searching, maps and directions, traffic, contacts list integration and "SMS a friend."
In even more mobile news to come out of 3GSM, InfoSpace announced a partnership with FAST to bring FAST's private-label search and advertising platform to InfoSpace's carrier partners in the U.S.; and AdStar announced plans to partner with Nokia to develop a private-label mobile advertising platform.
