People used to do this way back when. Here's a video from a 90's TV show called NetCafe. At some point they take a break to stream some downloads to the viewers. They ask you to plugin their TV Modem to get some random shareware. Then they show a screen with a rapidly animated 2d barcode for a couple minutes. http://www.archive.org/details/nc101_hackers

I wonder how many people actually owned a TV modem. It had to be a tiny market.

By the way, I highly recommend watching the episode, they interview Aleph One and some other old-school hackers.
