Assuming you are only talking about last-mile video service.
If you bring data service into the mix, it drops down to Cable vs. "Ma Bell". While Sattelite technically have data solutions, they no longer qualify as "broadband" under the new definition. In many locations, DSL service does not qualify as broadband either.
If you bring content into the mix, Comcast bought NBC Universal, which owns a large set of channels. They've been using that position and extorting their smaller competitors in certain markets. Time Warner also comes with a set of channels making the merged company even more powerful in contract negotiations with their competitors in markers where they overlap.
Comcast would continue to be the largest ISP in the United States, and would essentially gobble up #3. This makes them more and more powerful for lobbying, regulations and pretty much everything else.
