Yahoo announced Tuesday it would partner with Taiwan's High Tech Computer Corp. (HTC), the world's leading maker of mobile phones running Windows Mobile software, to add Yahoo to virtually all recent and new cell phone models that HTC makes.

The move is Yahoo's latest to make its services available to mobile customers, and the partnership would expand its base of mobile Internet users by millions, Reuters reports.

Yahoo says Windows Mobile users are a good fit for the company, as well as for potential advertisers. "Windows Mobile phone users tend to be consumers who are relatively data savvy," said Ojas Rege, senior director of Yahoo's mobile phone business.

"They are a pretty attractive group of users both from the standpoint of being early adopters of new services and in terms of advertising demographics."
