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!"
Here in Nashville, TN there's only one station that broadcasts their news in HD. CBS Affiliate WTVF. They've been in HD for a few months now and sort of brag about their ratings a bit, randomly playing "Thanks for making Channel 5 HD #1 (insert timeslots here)" and it seems like they're regularly beating the competition. I'm surprised the other stations are so slow to adopt this technology, it's not like HD is an 'early adopters' toy anymore.
