What can my grandparents do other than watch TV?

You don’t need to read this whole thing to answer the question, although hopefully it’ll give you a better understanding of where I’m coming from. 
————————-
My family lives with my grandparents, and between the two of them, (my grandparents) at least one of the three tv’s spread throughout the house is on from the moment they wake up around 8:00, untill midnight; My grandmother dose do some reading, cooking (with the TV in the kitchen on), and occasionally crossword puzzles, but that’s about it.

Now, yes I’m asking this question because the TV personally annoys me (I’ve grown to really dislike the negativity that’s in allot of shows [espesially the ones they watch, like the news for instance.] and commercials [some are good, but seriously, I just want all the stupid waist of time crap to leave me alone. That might sound a little recluse, but I think it’s quite the opposite as the lack of commercialism exposure frees me up to have real world experiences with real world people.]), but isn’t there something better that they can do other than sit around glued to a screen?

P.S. I think watching the tv is fine in reasonable doses, but all day, all night, all week is not reasonable…
