21st Century Fox's £11.7 billion acquisition of Sky has edged a little closer to being a done deal today, as the European Commission approved the merger. The commission was assessing any potential competition concerns that might arise from the marriage of huge media company and pay-TV provider. It concluded that as the two firms "are mainly active at different levels of the market," the acquisition wouldn't have any significant impact on competition. It wouldn't be good business for Fox to withhold its films from Sky's competitors, for example, or for Sky to worsen its platform by carrying Fox's content exclusively -- not to mention regulations and existing contracts in countries where Sky operates prevent that kind of thing from happening anyway.
