(Telecompaper) Yahoo announced new advertising and content services at CES, as well as another acquisition in the mobile sector. The acquisition is Aviate, an app to auto-categorize apps on Android devices and intelligently serve up apps and information based on a person's context, using functions such as the W-Fi, GPS or the accelerometer. Aviate, currently in private beta, is available to the first 25,000 people who download the app in the Google Play store and use the code "YAHOO" and will be integrated in Yahoo's mobile services this year. Also for mobile, Yahoo announced a News Digest for iPhone and iPod touch, built using insights from Summly. Yahoo News Digest delivers the most important news of the day, twice per day to a mobile device. For its main portal, Yahoo introduced Food and Tech magazines to offer news and images on the new subjects. It also announced its new, unified suite of digital advertising products for premium and audience-focused display, native and search advertising, which are accessible through a new buying platform. In addition, Tumblr Sponsored Posts now leverage Yahoo's technology to offer enhanced targeting, improved optimization and a new way to buy. Finally, Yahoo has upgraded its smart TV platform. The new platform will be demonstrated at CES, powered by Sigma and AmLogic reference platforms.
