New Year’s Eve countdown specials 2018: Mariah Carey is back. Here’s where to watch.

Usually, New Year’s Eve countdown specials come and go without much fanfare — unless there’s a real train wreck, such as Mariah Carey’s botched performance last year during ABC’s “New Year’s Rockin’ Eve.” Her representatives blamed technical difficulties and said “production set her up to fail”; the production company called those claims “defamatory, outrageous and frankly absurd.”

Apparently, everyone made up, because Carey returns to ABC on Sunday night: “We can all agree that last year didn’t go exactly as planned and we are thrilled to move forward together,” the two camps said in a statement. Here’s a roundup of all the shows leading the countdown to 2018:
