Ryan Seacrest is now officially the king of New Year's Eve.
The ubiquitous TV personality was hand-picked by Dick Clark in 2005 as his heir apparent to host the annual New Year's Rockin' Eve telecasts.
They shared the gig for several years while Clark, a TV and music industry legend, dealt with health issues after a 2004 stroke.
Clark died in April at age 82, so now ABC's star-studded ring-in-the-new-year show, a TV tradition for four decades, is called Dick Clark's New Year's Rockin' Eve With Ryan Seacrest.
The title pretty much says it all: ABC's 5 1/2 hours of programming -- which begins at 7 p.m. Monday, stops for 10 p.m. news and local New Year's Eve coverage from Victory Park in Dallas, then resumes at 12:30 a.m. -- will be fundamentally the same, just with a new host.
As Seacrest has said, why mess with a time-tested winning formula? It's all about enjoying music and witnessing the annual Times Square ball drop.
Not that ABC has the monopoly on New Year's Eve shows. There are several networks with rival broadcasts, each boasting an eclectic lineup of chart-topping musical guests.
Here are the highlights on Monday night:
New Year's Rockin' Eve Celebrates Dick Clark (7 p.m., WFAA/Channel 8): The network's marathon coverage opens with a two-hour tribute to Clark and his four decades of great musical guests and memorable moments. The first New Year's Rockin' Eve, airing on NBC in 1972, featured performances from Three Dog Night, Helen Reddy, Al Green, and Blood, Sweat and Tears. How the musical landscape has changed since then. Fergie, of Black Eyed Peas fame, and Jenny McCarthy are hosts.
Dick Clark's New Year's Rockin' Eve With Ryan Seacrest (9 p.m., WFAA/Channel 8): Seacrest hosts from New York's Times Square, while Fergie oversees the Los Angeles-based portions of the telecast. The show features an all-star musical lineup performing 15 No. 1 hits. The New York talent includes Taylor Swift, Carly Rae Jepsen, Neon Trees and Psy in Times Square. The West Coast party features Justin Bieber, Jason Aldean, Greyson Chance, Brandy, Flo Rida, Karmin, OneRepublic, Pitbull, Ellie Goulding and the Wanted. The after-midnight portion of ABC's programming, beginning here at 12:30, will wrap up at about 3:15 a.m.
Big D NYE (10:30 p.m., WFAA/Channel 8): Coverage of the sixth annual New Year's Eve celebration in Victory Park, hosted by Pete Delkus and Dale Hansen, will last two hours. In addition to fireworks, there will be musical performances by Breaking Southwest, Forever the Sickest Kids, Leogun, Pentatonix and DJ Ro Parrish.
New Year's Eve With Carson Daly (9 p.m., KXAS/Channel 5): NBC's two hours of New York-based coverage will be split, with one hour on prime time, the other beginning at 11:30 p.m. Musical performers include Train and The Voice winner Cassadee Pope. Angela Kinsey of The Office will provide live reports from Times Square. Taped segments will feature such NBC personalities as Amy Poehler, Nick Offerman, Jay Leno, Jimmy Fallon and Donald Trump.
New Year's Eve Live! (11 p.m., KDFW/Channel 4): This 90-minute show comes from Mandalay Bay Resort & Casino in Las Vegas, although the network will cut to New York to show the ball drop. Musical performers include Lifehouse, Phillip Phillips and Carmen Electra.
Live From Lincoln Center (7 p.m., KERA/Channel 13): Before he died in August, renowned composer-conductor Marvin Hamlisch was scheduled to conduct the New York Philharmonic's 2012 New Year's Eve program. The orchestra instead will dedicate its annual event to this icon of American music, with a live broadcast called One Singular Sensation: Celebrating Marvin Hamlisch. Host Audra McDonald will be among the artists performing. Others include Joshua Bell, Raul Esparza, Michael Feinstein, Maria Friedman, Josh Groban, Megan Hilty, Kelli O'Hara and Frederica von Stade.
All-American New Year's Eve (10 p.m., Fox News): Bill Hemmer and Megyn Kelly host this 90-minute show, which includes musical performances by Pat Benatar, Sarah Brightman and the cast of Broadway's Million Dollar Quartet.
TLC's 11-hour Cake Boss marathon begins at 3 p.m. and includes a new episode of Next Great Baker at 8 p.m. Fittingly, the new show has a "New Year's Eve, Hoboken Style" theme.
Turner Classic Movies airs a lineup of three films with New Year's Eve settings: After the Thin Man (7 p.m.), The Apartment (9 p.m.) and the Rat Pack's original version of Ocean's Eleven (11:15 p.m.).
Nick at Nite rings in the new year with three New Year's Eve-themed Friends episodes, beginning at 11 p.m. It fittingly closes with Monica, Ross and Joey dancing on Dick Clark's New Year's Rockin' Eve.
HBO airs New Year's Eve, the 2011 romantic comedy with an all-star cast that includes Robert De Niro, Michelle Pfeiffer and Ashton Kutcher, at 8 p.m.
