Comcast and Time Warner Cable could offload between 3 million and 5 million customers to Charter Communications, according to a Financial Times report. Executives from all three companies have met in recent days and negotiations remain ongoing, the report says. Selling off a sizable chunk of customers could help better the odds of Comcast’s TWC acquisition getting a thumbs up from federal regulators. The company has already said it’s willing to sell 3 million subscribers to a competing cable provider if the historic buyout is approved.
