Why is "watching on Laptop/PC/Tablet" always associated with "watching alone"?
I have a very old TV (about 15 years old now), which I use to play WII games and watching soccer during international championchips (The streams are horrible at the time), but I don't use it for anything else.
When I have friends over to watch stuff (DVD, File or stream), we use my Computer (Its screen is 19" if I am not mistaken and hence biggern then my ancient TV Screen anyway). There you don't (or seldom) have ad-breaks in the middle of stuff, you can watch anything at anytime, you can binge watch if you so choose, you can pause at any time you want. All those arguments count againts watching anything on a regular TV Screen.
An other friend did away with TV entirely and has everything connected to his projector and hence watches everything from games to Bluerays on his entire wall. (Ok, maybee not in the best HD possible, but heh, who needs that when they can watch in ~ 3 meters by 5 meters)
So: Just because we don't use a TV or watch the stuff they provide on cable doesn't mean we are always watching everything on our own...
We just use an other Device and an other source, but still like to watch stuff as a group.
