Maybe? Between the DVR and TV from non-ad sources, we rarely see any commercials at all -- and yet my wife and I both routinely have another screen up during SOME shows. We find there are two kinds of movies/TV: stuff that's kinda just relaxing and during which you can browse twitter or whatever, and stuff that's more serious where you can't really multitask without missing important aspects of the show, either because of the filming style or the density of the material or the pace of events or whatever. The canonical example of the latter is The Wire. More recently, I'd put The Crown or Watchmen in this category. For the former, well, pretty much any traditional network show counts. However, even in high-attention programming, it's pretty common for one of us to pause the show and check a screen to verify where we saw a given actor before, or look up a related bit of information (e.g., during the Crown, we often check on historical context).
