Capitalism, thinly veiled adverts
@Jo no you see Mamma Mia! (company owned by universal) is paying large amounts of money to Universal TV (company owned by universal) which means that Mamma Mia! doesn't have to pay as much money to anyone who's entitled to a cut of net profits from the film and universal (which owns both companies) can keep more!
