For the second year in a row, Netlflix’s original content made a big splah in the Emmy Nominations that were released yesterday:

Three Netflix series collected 15 prime-time Emmy nominations in the highest profile categories on Thursday, fluffing up the industry cred that the online subscription service has been grooming with its edgy original programming.

Netflix, the online subscription video service with the most subscribers, has been using original shows like “Orange Is the New Black,” “House of Cards,” and “Derek” to cast itself in the mold of a television network more than the video library and DVD-by-mail service that are its roots. Netflix has credited its award-snagging, buzzed-about originals for boosting its subscriber rolls, though it defers from providing any direct links between original content and subscriptions. Traditional Hollywood players have grumbled about Netflix’s bragging about hits without providing hard viewership stats like ratings.

On Thursday, “Orange Is the New Black” was nominated for outstanding comedy series. The show, set in a women’s prison, also received nominations for the program’s writing and directing — an episode helmed by Jodie Foster got the nod. Taylor Schilling was nominated for best actress in her role playing protagonist Piper. Kate Mulgrew, who plays Red, was nominated for best supporting actress. Three others were in the running for outstanding guest actresses: Natasha Lyonne as Nicky Nichols, Uzo Aduba as Suzanne “Crazy Eyes” Warren, and Laverne Cox as Sophia Burset.

Ricky Gervais, star of “Derek,” was nominated for best actor in a comedy series. Netflix embraces “Derek” as one of its originals, though the program was aired in England on traditional television before it “debuted” on Netflix in the US. The comedy drama follow a middle-aged man who works in a nursing home.

“House of Cards,” a political drama, again rounded up a slew of nominations, after several last year and one win for directing. The program was nominated for best drama, best writing, and best directing. Stars Robin Wright and Kevin Spacey are candidates in the best acting categories, and Kate Mara’s brief appearance earned her an outstanding guest actress nominHoation.

Last year, Netflix picked up nominations for both House Of Cards and Orange Is The New Black, although neither show won in any of the categories in which it had been nominated. Several of the reports this year, meanwhile, have noted that Netflix has received another round of nominations while its competing online streaming service Amazon Prime Instant Video did not even though it too has several original run series available at this time. As The Huffington Post’s Alexis Kleinman notes, though, the real battle seems to be between Netflix and HBO:

HBO may be the king of Emmy nominations, but Netflix is fast becoming a threat to the throne.

HBO got 99 of the Emmy nominations announced on Thursday, the 14th year in a row the cable network has gotten more nods than any of its rivals. It also produced the show with the most nominations: “Game Of Thrones,” with 19.

But Netflix garnered 31 nominations more than doubling last year’s haul of 14. That puts Netflix at 7th on the list of networks getting nominations, but it is climbing up the ranks quickly. And the networks ahead of it are all “real” TV networks like CBS and ABC. Their nomination tallies aren’t growing as fast.

And Netflix is the more efficient nomination-getter: HBO’s 99 nominations are for a total of 26 shows, miniseries, movies and specials. Netflix’s 31 nominations were for just 5 shows, specials and movies. That comes out to an average of 3.8 nominations per show for HBO and just over 6 per show for Netflix.

What’s perhaps most surprising is that Netflix is a website, not a traditional TV channel. Netflix has only been around for 17 years, while HBO has been around for 42.

HBO may have had a head start, but it might not be long before Netflix catches up. Netflix only has a small amount of content made exclusively for the site. That could change as the site grows. Last year was the first year that shows created expressly for online streaming were nominated for Emmys, and people are increasingly watching shows online.

As the quality of online streaming original programming like this continues to get better over time, we can expect Netflix and someday Amazon to become more competitive with HBO and other networks when it comes to garnering these awards. This year, most likely, we’ll still see the big awards go to the more traditional networks, but that’s not going to last forever.

The other notable fact is that, like last year, none of the drama series nominated for an Emmy this year come from any of the broadcast networks. They are all either from a free or paid cable network, or Netflix.
