CNBC’s Silicon Valley Bureau Chief Jim Goldman is in Las Vegas for the 40th annual Consumer Electronics Show--where some 140,000 people are previewing products from 3,000 companies over the next four days. Our top tech reporter appeared on “Squawk on the Street” to tell us the companies – and stocks – to watch at the conference.

The theme this year is the digital living room, with Bill Gates of Microsoft focusing his keynote address on the topic. A good portion of the tech being introduced revolves around the “home hub,” which is channeling all the user’s communication, entertainment and personal information through the television.
