Even on Sundays there are a lot of newspapers--eight national Sunday newspapers sell about 17 million copies. Most of these are delivered to people's houses, so they can be read over a late Sun- day breakfast.
As well .as the national newspapers, there are over 110 local morning and evening papers. There are weekly newspapers.
All these newspapers have a common history, which goes back to the 1600s. At that time groups of writers collected news and stories about famous people from the coffee houses in the city of London, and sent the news to towns and villages in the form of letters.
