Onstage at CES today, Marissa Mayer announced that Yahoo had acquired Aviate, an Android app that shows users a dynamic home screen with the best apps and information it thinks they need. The purchase fits into Mayer's ongoing strategy of creating personalized mobile software that becomes a daily habit. No purchase price was announced, but Aviate has raised a little under $2 million in financing to date.

Marissa Mayer has been snapping up startups since she took over, in large part to build out her ranks of young mobile developers. Counting Aviate, Yahoo has acquired 31 startups since Mayer took over in July of 2012.
