T20 is the fastest form of cricket, with lots of action and games that are over in a few hours. Mostly the tournament is in the Caribbean but 16 games are being played in the U.S. where a growing South Asian population is slowly increasing (from a base of basically nothing) interest in the sport.
This tournament is a big deal. Cricket is a massive international sport with hundreds of millions of fans in India alone. There'll be tremendous interest before Australia's near inevitable triumph

Edit: I originally said a few games are in the U.S. It appears to be 16. Four in Texas and Florida and eight in New York. The stadium in New York, on Long Island, will have temporary stands for 34,000 people and has been built in record time. After the tournament the stands will be dismantled but the cricket ground will remain. About $US2.7 million is predicted to flow into the Nassau County economy.
