While major studios have taken some library TV shows off Netflix, the on-demand provider is adding new, in-house TV-produced series.

In June, Netflix had 14 newer TV series on the air -- those made in the last three years -- which is more than triple the next-highest TV/movie studio, according to MoffettNathanson Research.

Comcast-owned TV networks had four TV shows during the month that were three years or younger, while The CW had three and Time Warner, CBS, Walt Disney and Sony had two each. Viacom and Fox each had one.

Overall, of the top 500 TV shows according to TV-movie site IMDB, 187 shows were streamed on Netflix in June.

Recently, big studios made news by shifting some programming off Netflix to their own digital platforms -- FX to its FX+ service and NBCUniversal programs, such as “30 Rock” and “Parenthood,” going to Hulu. These shifts came after Walt Disney said it would take movie product off Netflix for its own SVOD platform.

MoffettNathanson, partnering with YipitData, forged a "Rating Power" index to gauge the popularity weight of Hollywood studios content on Netflix. It defines rating power by looking at IMDB's star ratings times the number of IMDB's total reviews times the number of episodes.

In June, Fox posted the greatest share of total Netflix rating-power numbers: 24%. CBS was at 16%; The CW, 13%; Time Warner, 12%; Walt Disney, 9%; Comcast, 6%; Sony, 5%; Netflix, 4% and AMC Networks, 4%.

Netflix continues to sharply ramp up TV production; it plans to spend $7 billion in TV-movie production this year.
