In addition to hosting The Voice, Daly also hosted his very own New Year's Eve special on NBC, live from Times Square.

In 2011, Daly began hosting the NBC singing competition The Voice in which contestants will sing for the four coaches for a shot at a record deal with Universal Music Group and $100,000. He hosted the Blind Auditions, the Battle and Knockout Rounds, and the live shows twice a week (Mondays and Tuesdays). Daly is also one of the executive producers of the Emmy Award winning show.
Carson Daly plays a small but pivotal role in the first episode of My Name Is Earl. While in the hospital after being hit by a car, Earl learns about karma from watching an episode of Last Call with Carson Daly where Daly claims that his success is a direct result of doing good things for other people. Earl is thus inspired by Carson Daly to turn his own life around, and sets out to make up for his many past wrongs. Carson Daly also had a small role on Dave Chappelle's show Chappelle's Show.
Daly became the "orange room" anchor (social media reporter) on the Today Show beginning in January 2013, and also serves as a fill-in anchor for Matt Lauer, Willie Geist and Lester Holt (weekends) when they are off.
