If Netflix had live soccer here in Uruguay, it would put all cable providers out of business - it MASSIVELY underprices them and has a vastly better service.
It's currently about U$ 40 for the cable tv basic package, as there's a flaunted "oligo"(mono)poly here, which even managed to outlaw Carlos Slim's company - he doesn't care because Uruguay is not a relevant market.
Local football matches and European football drive a lot of cable packages, along with HBO and kids' shows and series (which are mostly available on Netflix).
The same is true in the UK for Premiership Soccer, and I'm sure it's true for other sports in other countries.
