8. Second-screen experiences

"Second-screen experiences" is a buzz-phase among TV and movie execs these days. It refers to apps (mainly on the iPad) that listen to the audio output of your TV and display content related to the show or movie you're watching. The chances are that you already use your tablet computer or phone while watching TV, so there's ample opportunity to make the viewing experience a more interactive one.

Disney already has second-screen apps for movies such as "The Lion King" and "Bambi," while multiple TV networks have similar offerings: We can expect many, many more to be released in 2012.
