Let the hive mind of Engadget get that for you.
"I am looking for a device that will stream sound from one source to several recipients. For example, I want to stream sound from my TV or stereo to my phone or MP3 player that has radio and Bluetooth capabilities. I have looked into radio transmitters and they seem like a decent choice, but I can't find one that uses external power (USB or from the plug) and I would want one with a transmit range of around 50 meters. Thanks!"
Hmm, you must be counting a regional or local channel that I'm not.
I don't count the regional sports networks or NBC, CBS, Fox and ABC. The image above as well as their initial press release says, National. By definition any channel that isn't available throughout the nation isn't national. While NBC is available everywhere, it's not the same NBC, like it's the same Discovery.
