I can understand that they are not targeting those who regularly attend county cricket, but how do you get the initiated to come along in large numbers? Whatever they say about the current t20 format, it has grown on the back of "genuine" supporters, alongside heavy marketing to get peripheral supporters involved. Plus, they are using smaller grounds that have much more atmosphere than, say, the likes of Old Trafford.
This seems to be an idea built on someone who's looked at countries where there is massive interest in the game (I.e. India and Bangladesh), where there are massive conurbations (at least in proportion to the country - I.e. Australia). Transferring this model to a country which has a long established set of tribal boundaries (I.e. Yorks vs Lancs) based on county rather than city, seems rather foolish.
