Look around the next time your on an airplane and see who still reads novels/books (either the analog or digital versions). Most 20/30 somethings are watching bad movies on their tablets while older people are the ones who still read.
Once upon a time, when you were outside your house, the ONLY thing you could do to entertain yourself was to read a book or a printed newspaper. Now there are a zillion other things you can do.
And yes, I think I read fewer books because it's so easy to surf the web, watch something via Netflix, or play some videogame instead of reading.
I am not sure if this is really such a bad thing as it sounds to old fogies.
