Yahoo CEO Marissa Mayer gave the keynote speech at the annual Consumer Electronics Show (CES) in Las Vegas. CES is a gathering of gadget geeks and tech enthusiasts, and Mayer's presence was a nod to Yahoo's place in the future of the Internet. 

Mayer emphasized the shift to mobile technology and announced Yahoo News Digest, news delivered to users twice a day. 

At some point, Katie Couric joined Mayer on stage. Couric, former TV talk-show host, was recently hired as global news anchor for Yahoo News.
