It's the state of Italian football unfortunately. Highest unemployment ever in Italy, coupled with the big teams having most of the fans, and a large chunk of those fans favoring tv subscriptions. People have no money. Plus the first few rounds of Copa Italia are generally not more interesting than the first few rounds of the FA Cup.
There are other reasons too, like fan culture and outdated stadiums, but the biggest factor is economical. It's been a crisis for a while now. Which is a little ironic, because the football is more fun to watch than it's been in a decade or so.
