I agree, but also find it surprising that younger generations are more focused on what they are watching.

I'm a background watcher for sure, and this trend with CC suggests to me that the whole "2nd screen" thing isn't playing with the younger generation.

Any insights as to why that may be?

To give more context, I was always a "background media" person. Even as a kid I'd draw while in front of the TV, I was never a focused participant.
