MTV network ended 2010 with the its largest year-over-year ratings gain since 1999, marking its fourth consecutive quarter of growth.

In the fourth quarter of 2010, the network saw a 24% increase in ratings from the same period a year earlier on gains across all major day parts.

The network saw a 16% increase in ratings among viewers within the 12 to 34 age range in the fourth quarter, according to Nielsen data.

The consecutive ratings gains were driven by its well-performing reality series programming. MTV's popular reality series,

Jersey Shore

, ranked as MTV's most-watched series ever and its ratings more than doubled in 2010, rising 119%.

"In 2010 we've seen enormous ratings growth as a result of the process we began almost two years ago to reinvent MTV for a new generation," MTV general manager Stephen Friedman said. "We look forward to a strong 2011 when we'll further diversify our lineup with new scripted series

Skins

and

Teen Wolf

alongside returning hits like

Jersey Shore

and

Teen Mom 2

."

This year, season two of

Teen Mom

saw its ratings climb 57% over season one's average.
