Maybe, but if they're a not-very-tech savvy older person buying this, they probably remember shows being free from over the air antennas and may think it is something like that.
Yes, in fact I have an antenna and a HDHomeRun nestled in my attic to record over the air shows that I occasionally consume.
But, I think it's far more common for people to have a TV service today, perhaps since comcast and their ilk push hard the TV/phone/internet bundle, and gone are the years when everyone would fiddle with the antennas on the back of their TV to get the right reception.
you are aware broadcast TV never ended?
