LOS ANGELES (AP) — "Mad Men," AMC's sleek drama set in the advertising world around 1960, and FX's legal thriller "Damages" made Emmy nominations history Thursday as the first basic cable programs to gain best-series nods for the television awards.

The HBO historical drama "John Adams" was the overall front-runner with 23 bids, including a lead-actor nomination for Paul Giamatti's turn as one of America's founding fathers.

"30 Rock," last year's best comedy Emmy winner, was the top nominee among sitcoms with 17 bids. "Mad Men" was the leading drama series contender with 16 nominations, including one for star Jon Hamm.

In the lead drama actor category, four of the five nominees were stars of cable shows, including Hamm.

Three best-actress nods also went to cable series stars, including Glenn Close of "Damages."

"I think it's changed the landscape of television," Close said of basic cable's growing creative strength.

HBO failed to field a best-drama series contender for the first time since 1998, after its now-departed "The Sopranos" claimed the honour last year. The premium cable channel still scored a leading 85 bids overall, followed by ABC with 76.

In addition to "30 Rock," other best comedy series nominees were "Curb Your Enthusiasm," "Entourage," "The Office" and "Two And a Half Men."

"The Wire," the just-ended, critically acclaimed HBO drama about police and drug dealers in Baltimore, lost its last shot at a best-drama nod after years of Emmy snubs. It received one nomination Thursday, for writing.

But other cable series made a serious dent in several top categories, gaining further ground on the networks. Broadcast favourites that failed to make a serious showing included "Grey's Anatomy" and "Desperate Housewives," both left out of the best-series categories.

"Grey's" stars Sandra Oh and Chandra Wilson received nominations — but the "Desperate" cast was shut out.

"Lost," rebounding with a well-received season, joined "Mad Men" and "Damages" in the best-drama series category with six nominees, including "Boston Legal, "Dexter" and "House."

Only one acting nomination went to "Lost," a best-supporting actor nod for Michael Emerson's role as the manipulative Ben.

Oh and Wilson are competing in the best supporting drama actress category that last year was won by castmate Katherine Heigl — who took herself out of the running this time, blaming her decision on lacklustre scripts.

Joining Hamm with lead drama acting nods were last year's winner James Spader, "Boston Legal," Bryan Cranston of "Breaking Bad," Michael C. Hall, "Dexter," Hugh Laurie, "House" and Gabriel Byrne, "In Treatment."

"I'm surprised," Hamm said. "For someone like me to be included is amazing. Look at this list: These are people I've been watching, and been a fan of, for years and years. It's a genuinely wonderful feeling."

Close's competition for lead drama actress honours includes 2007 winner Sally Field for "Brothers & Sisters," Kyra Sedgwick, "The Closer," Mariska Hargitay, "Law & Order: Special Victims Unit" and Holly Hunter, "Saving Grace."

"I'm very honoured," Field said in an e-mail. "It never gets old. I do, but it doesn't."

"Damages," in which Close plays a tough-as-nails litigator, won critical acclaim last year but not great ratings. Close is hoping the Emmy attention will boost the show's audience for season two.

"We need all the help we can get," said Close, who was being driven to a shooting location on Long Island when her sister, Nancy, called her cell phone with the nomination news.

As for her nomination, she was more sanguine.

"I don't believe in comparison among artists," she said, "but, given the amazing number of talented people in this profession, to be included with a distinguished group of people is a huge honour."

Actresses nominated for best comedy series were Tina Fey of "30 Rock," the series she created; last year's honouree America Ferrera of "Ugly Betty," Christina Applegate, "Samantha Who?" and Mary-Louise Parker, "Weeds."

Nods for comedy series lead actors went to Tony Shalhoub for "Monk," Steve Carrell, "The Office," Lee Pace, "Pushing Daisies," Alec Baldwin, "30 Rock" and Charlie Sheen, "Two And A Half Men."

Ryan Seacrest, host of top-rated series "American Idol" made the cut in the new category of best host for a reality or reality-competition show.

Other nominees were Howie Mandel of "Deal or No Deal," Heidi Klum of "Project Runway," Jeff Probst of "Survivor" and Tom Bergeron of "Dancing with the Stars."

"I'm thrilled that they've added this category, and thrilled to be part of this virgin group, if you will," Bergeron said.

The "Dancing" host said he debated whether to watch the announcement: "You know, there's that sort of weird sort of superstitious-think, like, 'Well, if I don't watch, maybe I'll get nominated, but if I do watch, I won't.' Like that's gonna change anything."

Nominees in the top categories for the 60th Annual Primetime Emmy Awards were announced at the Academy of Television Arts & Sciences by Kristin Chenoweth, Neil Patrick Harris and TV academy Chairman John Shaffner.

Shaffner surprised Harris and Chenoweth at the end of the telecast by announcing supporting-actor nominations for each. Chenoweth, of "Pushing Daisies," stood open-jawed, while Harris, the regular scene-stealer of "How I Met Your Mother," pumped his fist and exclaimed, "Nice!"

The trio then blew out candles on a birthday cake to celebrate the Emmys' 60th anniversary.

Besides ABC's 76 nods, the broadcast networks tallies were CBS, 51 nominations; NBC, 50 and Fox, 28. PBS had 33 bids, while AMC garnered 20 bids.

The Emmy Awards ceremony will be held September 21 and broadcast on ABC.

Other Emmy honours, including those for technical achievement and guest actors and actresses in series, will be given at the creative arts ceremony on September 13.
