One summer I was actually reading two books per day: A Louis L'Amour Western in the morning and a Mickey Spillane Mike Hammer book at night.
But the vast majority of Americans haven't read a book since they got out of high school or college due to the fact that they watch the television.
I started reading a lot of books during the TV commercials. But what would happen is that I found the books so interesting that I quickly didn't bother even watching the TV shows after the commercial breaks and stuck with the books. BTW, a LOT of book reading can be done while waiting in line at the Post Office (especially around Christmas time), sitting at the airport, on air flights, or just as an excuse not to have to talk to annoying In-Laws during the holidays.
