Which MTV series made Carson Daly its original host before he moved to late-night television?

Total Request Live made Carson Daly its original host before his move to late-night television.

Total Request Live, usually called TRL, premiered on MTV in 1998 as a live countdown of viewers’ favorite music videos. Daly hosted the program from its launch and became strongly associated with its Times Square studio, where fans gathered to see visiting musicians and pop stars.

The show became a major platform for late-1990s and early-2000s teen pop, hip-hop, and rock. Its daily format encouraged viewers to influence the countdown through requests, making it an early example of interactive music television.

Carson Daly later became the host of Last Call with Carson Daly on NBC, followed by a prominent role on The Voice. TRL itself returned in later versions, but Daly’s original run remains the one most associated with MTV’s peak countdown era.
