Comcast's deal to buy a majority stake in NBC Universal from General Electric should put to rest fears at the cable operator that King Content will kill its business. But even if it becomes a thoroughfare of programming genius, the new venture will still have to convince a skeptical marketplace. The train wreck of Time Warner-AOL threw the idea of new media into financial purgatory.

Just how the venture will wring savings from its disparate businesses and avoid suffocating regulatory scrutiny are issues that could also create Comcastic headaches.  Robert MacMillan points out on our Mediafile blog, with a sensible dose of skepticism, that the new venture is affirming its commitment to local news, in effect, promising to keep the garden hoses pumping even as it primes for a media gusher with big-ticket programming.

Still, while making a new media juggernaut could still turn out to be a pipe dream, Comcast CEO Brian Roberts (pictured above) cannot be faulted for allowing his company to get stuck in a dumb pipe nightmare.
