What is an over?

An over is the collection of six deliveries that a bowler sends down to the batsman. In English first class cricket, the number of balls per over was not six, but 4 until 1888. Then it became five per over until 1899. Since 1900 it has been six. The ‘over-rate’ is the number of overs bowled per hour. Eight balls per over were tried in the 1939 season.
