Here’s a way for parents to ensure their kids are doing their homework instead of watching television: TV-B-Gone. It’s a $14.99 device that can turn off every model of U.S. Asian, and European television, all with a single click. The website for the device is undergoing reconstruction right now, due to heavy Internet traffic. I’d be interested to know the range of this thing — can a person using it drive down a neighborhood street turning off all the televisions on the block?
