I disagree vish while the world market is in theory unlimited I think it is limited people want to follow sports they can relate to and that means see. You will always get fans who will follow overseas games on TV but those are limited. The growth in the future is likely to be China India and South America while they may watch premiership football it's unlikely to be their main sport they will want a national sport of their own. The uk based fans and thiose of nearby countries Ireland and Scandinavia will always be the main source of income I feel.
I cannot agree with this. Scandinavia has a population of roughly 21 million and Ireland of around 6 million . Lets say together they have a population of 30million.
China has a population of 1.4 billion, India 1.25 billion...
So if every person from Scandivia and Ireland were a fan, a paying fan, that would give you 30million customers. Now lets say they each spend 3 times as much as a Chinese or Indian fan (which isn't the case but anyway). That would give you the equivalent of 90 million paying fans.
That is the equivalent of just 3% of China's and India's population....not taking into account the continent of South America, the United States or the entire continent of Africa, or Malaysia or the Phillipines.
Lets not forget that this is wildly assuming that 100% of Scandinavia's and Ireland's population are premier league fans.
The global market dwarfs the "local" or even "European" market in size in terms of football revenue.
