Mayer discloses Yahoo acquisition, unveils app and tech site at CES

|By:, SA News Editor

During a CES event (live blog), Marissa Mayer announces Yahoo (YHOO) has acquired Aviate, developer of a service that recommends apps based on location and time. She says Aviate's technology will be used to help further personalize Yahoo's apps and sites.

Mayer has also unveiled Yahoo News Digest, an app that leverages Summly's content summarization tech to provide twice-a-day news digests containing articles, photos, tweets, and other content, and Yahoo Tech, an expected tech news site spearheaded by ex-NYT columnist David Pogue.

Pogue asserts Yahoo Tech will serve "the middle 85% of normal people," and takes some shots at rival tech news sites along the way. Interestingly, the site won't be monetized via banner ads.

Also: 1) Mayer suggests Yahoo will focus on improving its share-losing search service by emphasizing contextual search; Google is no stranger to the concept. 2) Katie Couric says her Yahoo show will focus on interviewing "anyone who we believe has an important and interesting story to tell." 3) Tumblr CEO David Karp claims average engagement per Tumblr user is up 55% Y/Y.

Meanwhile, BI reports Yahoo is working with startup Celltick to create a custom Android home screen, one that will promote Yahoo apps/services and adapt to user activity. Facebook took a shot at this concept last year, with less than stellar results.
