I think T20 was invented to get other European nations and US to play the game. This is a mardanga type game, in which 10 runs/over is possible. Plus, the games are typically over in 3 hours or less. If the Americans can enjoy a super boring game of baseball, then if ICC markets T20 properly with a 10-year horizon, T20 may become popular here. ICC will need to have some exhibitions and tournaments in the areas with large population from the Indian subcontinent and WI. They absolutely need to put the games on TV, even if they have to pay. Without proper marketing and promotion, T20 will also be a 10-nation sport.
