i don't know really how much it was back then, but not to much. there wasn't more than one or two shows in a day that i was interested in, often it was less, so maybe 5-10 hours per week?
i can tell you that now i spend an average of 1 to 1.5 hours per day watching movies, series or youtube. there are to many other interesting things to do that i also want to spend time on (like discussing on HN :-)
