Yahoo Chief Executive Terry Semel is scheduled to announce today the Yahoo Go initiative, which will make available its email, instant messenger, search, photo and other services on mobile phones, PC-connected TVs and personal computers without using a browser, writes CNET. Yahoo Go Mobile, available starting today, will be preloaded on Nokia Series 60 mobile phones and available to Cingular and AT&T customers in the U.S.

Yahoo Go TV will be available before April and will make entertainment-related services (including local and video search, content from CNN and MTV, movie trailers and movie times, TV shows, news from My Yahoo) available on PC-connected TVs through a downloadable application on the PC; it is free, but will be ad-supported.

Yahoo Go Desktop will consist of a suite of services available on PCs without relying on a browser, including a dashboard providing access to Flickr photos, Yahoo Messenger, news, Web search, address book and calendar as well as blogs, photos and other items posted to Yahoo 360.

Yahoo also plans to launch a service allowing mobile users to program the recording of TV shows remotely over mobile phones; it will also offer music services through the TV.
