The Big Bash League (often abbreviated to BBL or Big Bash) is an Australian professional franchise Twenty20 cricket league, which was established in 2011 by Cricket Australia. The Big Bash League replaced the previous competition, the KFC Twenty20 Big Bash, and features eight city-based franchises instead of the six state teams which had participated previously. The competition has been sponsored by fast food chicken outlet KFC since its inception. It is one of the two T20 cricket leagues, alongside the Indian Premier League, to feature amongst the top ten domestic sport leagues in average attendance. The winner of BBL 09 (2019/2020) was the Sydney Sixers who beat the Melbourne Stars by 19 runs in the final. The Sydney Sixers took the title from the Melbourne Renegades who beat the Melbourne Stars in the BBL 08 (2018/2019) final.
BBL matches are played in Australia during the southern hemisphere summer, in the months of December, January and February.
