CBS will be using Bluetooth technology to beam video clips of five of their new primetime shows to your cellphone, smartphone, or PDA (provided you device has Bluetooth as well) from inside of the Grand Central Terminal train station in NYC. The shows featured will be Shark, Smith, Jericho, The Class and CSI. Users will be required to accept the video before viewing, and the 30-second clips will take approximately 20 seconds to download. This is a very cool idea, and hopefully one that catches on. Imagine going to the grocery store, seeing an ad for a new dinner entrÃ©, and downloading a video that shows you how to prepare that dish, hosted by Emeril Lagasse. Bam! Interactively amazing.
