Yikes!

According to Nielsen, 12-17 year olds spend nearly the same amount of time viewing TV in bedrooms as they do in family rooms. Overall, teenagers spent 47 percent of their total TV viewing in their bedrooms versus 48 percent in family rooms.

According to the Nielsen data, the 12-17 year old demographic watches more television in the bedroom than any other age group.

In contrast, the 35-64 demo spends 62 percent of their total TV in a shared space and only 31 percent of their time in the bedroom. Those 65 and older spend the largest chunk of their viewing time (69%) in a family or living room.
