Speed it up
Crickwet as it standss does not lend itself well to audiovisual media coverage. Not even many Brits I know follow cricket live broadcasts. You have to be there to enjoy it, I'm told.
Now, if someone invented a variant of cricket that is faster and a little more spectacular, that could change its fortunes worldwide in the course of the 20th century. It would still have to reckon with football (Association Football, that is) as a contender for mass attention, but I think it would have chances.
Plus, in terms of numbers I think more people worldwide follow cricket than either baseball, basketball, or American Football. It's only association Football that's bigger statistically IIRC. Problem is. most cricket fans are too poor to be good advertising targets, living in India, Pakistan, ZImbabwe, Kenya and other places like that.
