Comcast will separate its media and connectivity businesses, dismantling an earlier bet on combined entertainment and distribution. The split comes as both the media and telecom landscapes have become increasingly competitive, says Mike Cavanagh, who is currently Comcast's co-chief executive and will lead NCBUniversal as a standalone company. "That pace of change continues to accelerate, and so, we simply don't see these conditions changing anytime soon," he says. Where we previously believed that scale and the diversification benefits warranted operating these businesses as one company, we've now simply changed our mind about that." ([email protected])
