Monopoly does this to the markets. Movistar (Telefonica) is the de-facto owner of high-stakes sports in Spain. This means Football (Spanish league, Champions League), Tennis (all the Masters and Grand Slams), Basketball, you name it.

They are also the main telco in Spain, so they own the service and the channel.
