The origin of Twenty20 Cricket,
Dr George Christos 1997
media release, 5 Jan 2009article in the West Australian Newspaper, 6 Jan. 2009
(above webpage taken down by WA News, here is a photo)[Dr Christos was in constant contact with the ICC and the EWCB
during the period 1996-2000 about the one-day cricket rain rule,
so it is preposterous to suggest, as the ICC does in this article,
that they receive lots of letters and do not remember
the letter of 2 May 1997 from Dr Christos.]
The idea of 20/20 cricket was actually put forward to the ICC and the EWCB in a letter dated 2 May 1997 by Dr George Christos, a mathematician, at Curtin University, Perth, Western Australia. His
letter, not only puts forward the idea of 20/20 cricket, but clearly
outlines why it will be a huge success. Dr Christos, came up with this
idea while working on a rain-rule for one-day 50-over cricket (called
the ‘wicket-averaging method’), which was considered by the ICC, but
who chose to stay with the Duckworth-Lewis method. Dr Christos was
motivated to come up with a game (20/20 cricket) in which there would
be no need to use the Duckworth-Lewis method.

In a recent letter (3 pages) to the ICC, Dr George Christos writes to seek recognition of his intellectual property, Dec. 2008
to article published in "The Cricketer", December 1998 regarding his
'wicket-averaging method' rain-rule proposed to the ICC, which is
simpler to understand and play with, than the Duckworth-Lewis method,
and is cost free, unlike the Duckworth-Lewis method, which requires
software, updates to tables, and personnel.
