Second-screen technology was one of the big topics at the recent Cable Show in Washington, D.C. Motley Fool analyst Rex Moore was at the event and chatted with Akamai's (AKAM -0.11%) Kris Alexander about how so-called "couch commerce" is opening up new revenue streams for retailers, advertisers, and programmers.

In this segment, Kris talks about the explosion of connected devices such as Apple's (AAPL -0.35%) iPads and Google's (GOOGL 10.22%) Android tablets, and what it means for second-screen commerce.
