Were you one of the people who helped MTV or History see impressive growth in the past year?

A new report from Variety breaks down why these two channels did so well.

A look at the 52-week season that ended Sept. 18 shows that MTV grew by a sizable 34% year to year in adults 18-49 (to 776,000 viewers) and by 35% in adults 18-34, where it vaulted from fourth to first place, according to Nielsen. Its average primetime audience of 606,000 in the demo was even larger than struggling broadcaster CW (550,000), which was a non-factor in the summer when MTV dominated.

While MTV made some strides in the scripted arena with “Teen Wolf,” most of its damage was done by the unscripted likes of “Jersey Shore,” easily cable’s top-rated entertainment series in adults 18-49. Also, “Teen Mom” continues to shine in its shadows, standing as the No. 2 cable series in 18-34.

History, the network that was once known for its historical series and specials, had a great year with unscripted series “Pawn Stars,” “Ice Road Truckers” and “Ax Men.”

It was up 32% in 18-49 (to 906,000 viewers), rising to fourth from seventh place a year ago.
