      For one week in April, millions of people chose not to watch TV for “TV Turnoff Week”. TV Turnoff

Week started in 1995 and is more popular every year. Many people discover that you can have a good time

with the TV off. If that sounds crazy to you, just have a look at some numbers:

     ―An American teenager spends 900 hours every year at school; the same teenager spends 1,023 hours

every year watching TV. That's 2 hours 49 minutes every day. 

     ―An average (平均) British person (not just teenagers) watches 3 hours 35 minutes every day.

     ―In the US, most TV has adverts. American children see 20,000 adverts every year. By age 65, an

American has seen two million ads!

     But some research from Britain says that may not be a problem. The London Business School watched

people carefully during TV adverts and they discovered that people don't watch a lot of the ads. The

researchers discovered that the most common activity during the adverts was talking to other people in the

room. Many other people started reading or doing housework or changed channels during adverts. They

only really watched them about 25 percent of the time.
