confluence of forces. We can't sit still so want the control of being
able to pause. We don't mind and in fact prefer watching in solitude.
And when we're free isn't the same time as when our shows/games are
on. (I have a fourth reason: two 3+ hour football broadcasts can be
condensed to about an hour thanks to the wonders of fast forward,
freeing up five hours a week during football season.)
So we miss out on the communal experience that is watching something
with others, and/or talking about it the next morning. But we're OK
with that. Just don't tell us who won the game or The Bachelor too
soon after it's over.
