The EU's anti-trust regulator on Thursday accused six major Hollywood studios and Britain's Sky TV pay channel of using movie licenses to block access to their content in other EU countries.

"European consumers want to watch the pay-TV channels of their choice regardless of where they live or travel in the EU. Our EU economy Internet antitrust investigation shows that they cannot do this today," EU Competition Commissioner Margrethe Vestager said in a statement.

"We believe that this may be in breach of EU competition rules," she said.
