Obviously, the start of digital broadcasting and the 2009 digital cutover were the biggest things to happen to broadcast TV in decades. Since then, we've seen some new antenna manufacturers show up, some small tweaking to antenna and amplifier designs (with some worsening), and some new channels pop up in various markets.
So what's next? The occasional new channel, something cool on the technology front, or something else entirely?
(Hoping this doesn't turn into a they'll-kill-OTA thread, but so it goes.)
