The 64th Primetime Emmy Awards kick off at 8 p.m. ET/ 5 p.m. PT on ABC live from the Nokia Theater in Los Angeles. Late-night talk show host Jimmy Kimmel will host the Emmy ceremony for the first time.
Another Emmys first-timer, Showtime's "Homeland," is shaking up a few races with its nominations for Outstanding Drama Series, Lead Actor and Lead Actress. Meanwhile, "Downton Abbey" entered the Drama Series category instead of the Miniseries/Movie race for the first time and scored seven total nominations.
On the comedy front, another newcomer, HBO's "Girls," picked up Emmy nods in the main Comedy Series category, and series creator Lena Dunham earned a nod for Lead Actress in a Comedy Series.
Records could be set at the 2012 Emmys as well. Sunday's ceremony gives "Mad Men" a chance to win its fifth Emmy for Best Drama, surpassing fellow record holders "Hill Street Blues," "L.A. Law" and "The West Wing."
