Limited overs cricket

In the 1960s, English county teams began playing a version of cricket with games of only one innings each and a maximum number of overs per innings. Starting in 1963 as a knockout competition only, limited overs grew in popularity and in 1969 a national league was created which consequently caused a reduction in the number of matches in the County Championship.
Although many "traditional" cricket fans objected to the shorter form of the game, limited overs cricket did have the advantage of delivering a result to spectators within a single day; it did improve cricket's appeal to younger or busier people; and it did prove commercially successful.
The first limited overs international match took place at Melbourne Cricket Ground in 1971 as a time-filler after a Test match had been abandoned because of heavy rain on the opening days. It was tried simply as an experiment and to give the players some exercise, but turned out to be immensely popular. Limited overs internationals (LOIs or ODIs, after One-day Internationals) have since grown to become a massively popular form of the game, especially for busy people who want to be able to see a whole match. The International Cricket Council reacted to this development by organising the first Cricket World Cup in England in 1975, with all the Test playing nations taking part.
Limited overs cricket increased television ratings for cricket coverage. Televised coverage beginning with ODIs and quickly adopted for test coverage introduced in-depth statistics, graphical analysis, cameras in the stumps, shots from many angles, high speed photography and various technologies to enable television viewers to judge caught behind decisions, runouts, and lbw with far better information than the umpires.
In 1992, the use of Third Umpires adjudicating runouts with television replays was introduced in the test series between South Africa and India. The first player to be called out by television replay was Sachin Tendulkar. The use of third umpires has expanded steadily to other types of disputed umpiring calls since then.
