I have just set up PiVPN on a Raspberry Pi that I have left over.
I'm going to install it next weekend at my parents home so that I'm able to use their IPTV.

I'm really impressed on how easy it is to set up.
Wish me luck

Prediction:

1. Broadcast (free) TV will consist 100% of live programming

2. All series will be bought and available on streaming services like Amazon, Netflix, Disney+

3. Cable channels or TV episodes can be bought individually (iTunes, Google Videos, etc), basically they will be their own streaming service (it actually that already exists, IPTV? just not in the US?)

Why:

Everyone will use DVRs to record TV shows so can skip all advertisements

Therefore only way to get viewers eyeballs for ads is live programming where you need to cast votes which affect the outcomes (supposedly)

Streaming services obviously don't have this problem and don't need to run ads since there's a monthly subscription fee that more then covers cost.
