Peter Kafka explaining Comcast’s argument as to why it believes it should be allowed to purchase Time Warner Cable:

It’s okay for a giant cable company to buy another giant cable company, because cable companies don’t compete.

One protected monopoly purchasing another protected monopoly. I could imagine a world in which Comcast starts laying cable in an area that Time Warner currently controls. Enough lobbying could make that happen. But, in a world in which Comcast and Time Warner are the same company, it would never happen. That’s not good for customers.
