Let's suppose Comcast is successful in buying The Walt Disney Company and merging Comcast and Disney into a single company...
The resulting corporate name could be Comcast, or Comcast-Disney, or Disney-Comcast, or The Walt Disney Company, or Really Giagantic Media Co. Inc. (When NationsBank bought Bank of America, the resulting company was called Bank of America, but with the NationsBank logo.)
The Walt Disney Company today consists of four distinct segments: Media Networks, Consumer Products, Studio Entertainment, and Parks & Resorts.
The new, combined company would be likely to have a fifth segment, with a name such as Cable & Broadband or High Speed Distribution. And Media Networks would be likely to absorb Comcast's cable channels (as opposed to Comcast's cable distribution).
But Walt Disney World will remain Walt Disney World. And
Disneyland will remain Disneyland. And Walt Disney Pictures will remain Walt Disney Pictures. Brand is important.
