What are the speakers talking about?

W: You know, I’ve just finished some very interesting research for the newspaper about things people do in their spare time.
M: Really? What did you learn?
W: Well, I talked to 20 people, and 19 of them watch TV.
M: That’s interesting. You never watch it. Do you?
W: Not much. Anyway, about half of them, nine people play some kind of sport.
M: I’m not surprised. People are getting more exercises these days.
W: Yes. A few of them go to movies.
M: Mm, I do, too.
W: But here is the most interesting result. Only one of them reads.
M: That’s terrible.
