Las Vegas: More than half of the total 800 million monthly users of Yahoo! access it on their mobile phones, CEO Marissa Mayer said.

Mayer, while unveiling a suite of services covering digital advertising, food and technology, also announced the acquisition of Aviate, a mobile solutions company, in her keynote address at the CES 2014 here yesterday.

"We have been hard at work re-imagining Yahoo!'s core businesses across search, communications, media and video, all powered by two powerful platforms, Flickr and Tumblr. The response has been tremendous. This fall, for the first time ever, we surpassed 400 million monthly mobile users, which is about half of our 800 million total monthly users," she said.

Mayer stressed on the transformation of the firm from a technology company to a media, news, entertainment and advertising platform utilizing products focusing on search, communications, digital and videos.

She also launched News Digests, which will deliver top news events twice daily to users as well as digital magazines.

The company said the acquisition of Aviate, which develops mobile solutions especially for Android, will aid users to find local and personalized data. No financial details of the acquisition were revealed.
