What's interesting, is that when my parents saw my setup they immediately canceled their T.V. subscription with Comcast and bought 3 Chromcasts (one for each room) & a Netflix subscription, and switched to an antenna for their local news.
Once their friends saw this setup three or four of them setup the same thing.
It seems pretty popular among the older generations which grew up with antenna anyways, plus with the ease of using Chromecast, they can cut their bills down and get everything they want.
Unless you want to watch a lot of sports.
NCAAF is a little random since some games are on non-cable but a majority aren't. I'm on the west coast and the games are usually on FS1 or Pac-12 network.
NBA is pretty much impossible until the ABC has their Sunday games and the NBA finals.

OTA FOX only gets one or two playoffs games and the World Series.
In previous years it was possible to watch most of the games online via "live alternative video feeds (excluding the broadcast feed)", and now even that is not allowed.
