Having grown up without a television, I never understood this 'convenience' because whenever I watch a video, I cannot do another thing. I never learned to work with a television in the background, and as a result, if I don't give a video my full and undivided attention, I don't remember almost nothing from it. On the other hand, when I was a kid, I got used to listen to (news) radio while reading or doing other stuff. I have no trouble following an audio program while doing some other cognitive intensive task.

Of course, with the popularisation of using videos for "all the things" lately, I don't feel at home at many a (popular) website any more. But that's another matter entirely, I suppose.
