Univision Overtakes Comcast's (CMCSA) NBC in Key Demographics

Coming off their blockbuster acquisition of NBC from General Electric (NYSE:GE), Comcast (NASDAQ:CMCSA) is getting a look at the challenges they face as Univision surpassed NBC in viewers in key demographics of adults aged 18-34 and people aged 12-34.

Univision also said they're poised to become the No. 4 network after the February sweeps.

That's crucial to network television, as the sweeps determing the audiance a network is attracting, along with the advertising power they have.

That's bad news for Comcast in the early stages of its control of NBC, although not surprising for those who follow the weakened network.

NBC could be a drain on Comcast for some time, as it has struggled for years to generate interest from consumers.

Comcast was trading at $25.21, falling $0.07, or 0.28 percent, as of 2:39 PM EST.
