A new Nielsen report indicates that total viewing of broadcast and cable channels rose 1 percent to an average of 34 hours per person per week, according to The New York Times.

CBS was the most-watched network among all viewers for 51 out of 52 weeks, with three of its freshman series — Hawaii Five-0, Blue Bloods and Mike & Molly — landing in the top 20 for the year. (Incidentally, they were also the only new shows in the top 20.) While the migration of viewers from broadcast to cable continued, the lowest-rated broadcast network, NBC, still had twice as many viewers as the largest cable channel, USA.

In the world of cable news, Fox News remained the favorite, while MSNBC celebrated a historic win among all primetime viewers over CNN for the first time. VH1 and the Hallmark Channel, on the other hand, lost more than a quarter of their audiences this year.

Meanwhile, History grew by more than 25 percent this year, buoyed by cult hits like Pawn Stars and American Pickers. Investigation Discovery, or I.D., was another big gainer, with a 64 percent increase in viewership.
