During every world cup, certain TV channels acquire rights for live coverage of football games from the Fifa World Cup then they encrypt the channel in order to let people pay for subscription.
As for the World Cup 2014, the German channel ZDF acquired rights of coverage and ensured that everyone around the world will have the chance to watch the game for free.
ZDF channel director said that football is for the rich and the poor and everyone should have the chance to see the world cup 2014 game without having to pay for it.
This step came after court battles with the Qatari channel that is going to loose a lot of money after the coverage became for free whereby it won't be able to sell subscriptions anymore.
