by the time i had written this, i remembered that i foghot to mention Canada. basically USA and Canada are the two biggest PPV markets, followed by Australia and UK. i know most boxing is carried on TV-channels instead of PPV in the UK, as i just mentioned it. but thats what i meant that, occassional events are carried on PPV in UK and Australia, but majority events are shown on some TV-channel or another.
as for the PPV market in other countries of europe, or brazil. it is very small and barely gets more than a few thousand buys. as for japan, most boxing there is shown on WOWOW a subscription channel, or if its a japanese-event than any of the network channels like FUJI or TV-Tokyo. the UK is a rich country and yet so many people complain about PPV-model, in the developing world like Latin America or Eastern Europe, there are few who would bother to buy such a thing.
