Thirty years after its inaugural season, the Premier League can rightly celebrate its status as the world's most popular football league. There's not one factor behind it; there are many, and you might be familiar with them.
In no particular order, you might cite the following: heritage (the game was invented here, after all), language (English is the world's lingua franca), a very pro-business environment that facilitates foreign investment, strong leadership that regularly presents a united front (especially in the 15 years Richard Scudamore was in charge), excellent marketing and packaging/production values, a willingness to embrace expertise from abroad (not just players, but coaches, owners and executives too) and, often overlooked, a strong domestic market that is fiercely loyal and willing to spend on their club.
