The TV set in our bedroom died the other night, so I popped out to the local big-box appliance store to grab a new set. Setting it up required rescanning the channel spectrum. I guess I should mention that we don't have cable. Well, along with the other 40-something channels we get, a new one popped up, a noncommercial one that carries and promotes high-quality community access and educational content, most of which is in the 5-minute length category.
