The original football (soccer goal) actually consisted of tape - which stretched the whole length of the goal-line an two posts. This was later modified by the FA to goalposts and a solid crossbar, and the goals were reduced in size to 24 feet across by 8 feet in height.
The set of goals as we know them today came about because of a simple invention - the net at the back and sides of the goal - by a Liverpudlian engineer, John Brodie, back in 1889. Previous to this, there were many disputes as to whether the ball went over the line, so Brodie´s invention saved many arguments as to whether a goal had actually been scored. The Football League approved use of the goal-net in 1890.

At the establishment of the Canadian Amateur Hockey League (CAHL, 1898-1905), the Quebec team recommended that a rope be attached to the tops of the goal posts, and netting be attached to the posts and rope to form a pocket. After an exhibition series in 1899, the nets became a permanent item in the CAHL rinks.
