If you have 6 hours left in a day, then you shouldn't fill it in with an addiction or something unproductive. You should spend them on finding why you have 6 hrs left in a day, and try to fill those with real life.
Everyone needs a way to destress, to completely check out so to speak, of day to day life. As long as you aren't putting off seeing friends, dating, and other things, and - this is the biggy for me - you can stop at anytime without freaking out - then there's no problem with it.
Agreed with this. And it seems that the suggested maximum is 1-2hrs per day.

Addiction to television is just as real as addiction to video games. And in fact, it is likely much more common in the general population. Hence, the similar recommendation of television programming.
