M: Do you mind me changing the channel?
W: Go ahead.
M: What’s the news channel?
W: Try 12.
M: Oh, that’s it. Say, how do all these channels work?
W: If you have an ordinary TV, you can get the major networks on the local channels.
M: (12) What if someone wants to watch something like sports?
W: (12) You can buy channels on cable TV. Each channel offers something special, like sports, music or movies.
M: Can you buy as many channels as you want?
W: Sure. Do you have cable TV in Senegal?
M: No. Even in big cities we can only get two or three channels. In most places we can only get the Central Television. In larger cities we can get provincial TV and even municipal TV if the city has its own station.
W: What kinds of programs do you have on TV?
M: On weekdays we have teaching programs in the morning and afternoon with news. In the evenings we have news at about 7:30 and later, we have films or TV plays and other programs. (13) On Sundays we have films, operas, sports and children’s programs.
W: You’ve seen our TV ads. Do you have the same?
M: (14) We’re beginning to have ads but we never interrupt a program to show them. We have them only between programs.
W: Oh, that’s a good idea. Ads are so annoying. But we have them because the TV stations have to make money and companies pay a lot for ads. M: Well, that looks like the end of the news. (15) I think I’ll go study for my final exams next week.
W: (15) Yeah, me too. See you.
M: See you.
