After a two-hour salute to the late Dick Clark, ABC turns over prime-time hosting duties entirely to Ryan Seacrest. Scheduled to perform are Taylor Swift, Flo Rida and, just in case you needed to hear “Call Me Maybe” one more time in 2012, Carly Rae Jepsen. At 11:30 p.m. ET, after a break for local news, Seacrest returns to count down, for the first time, to the New Year – and the dropping of a ball that, for the first time, will have Dick Clark’s name engraved on it.
