When was the first Official (not friendly) T-20 match played?
As per Wikipedia the first ever T20 match was played on 13th June, 2003 between Durham and Nottinghamshire at Chester-le-Street.
The first international T20 match was played on 17th February, 2005 between Australia and New Zealand at Eden Park, Auckland.
I am sure I saw a Lancshire Yorshire T20 friendly at Old Trafford before the competition started properly in 2003. Can't find an evidence of it yet though.
