Hailing from Rockefeller Center in the heart of New York City, Jimmy has made it his mission to make sure viewers end the day with a smile. Each weeknight, he hosts A-list guests, from movie stars to athletes, comedians, public figures and everyone in between. He also delivers a signature nightly monologue, performs in topical comedy sketches, plays fan-favorite games, and presents recurring segments like Thank You Notes. Today's popular musical guests also stop by to perform alongside house band The Roots.

Live from New York for more than four decades, celebrity hosts join an award-winning ensemble cast to perform comedic sketches, satirical news and digital shorts, alongside popular musical acts. Capturing the pop-culture zeitgeist, the show's sketches and segments often go viral the next day. Over the years, cast members have included Jimmy Fallon, Will Ferrell, Tina Fey, Kate McKinnon, Seth Meyers, Eddie Murphy, Bill Murray, Mike Myers, Amy Poehler, Chris Rock, Maya Rudolph, Andy Samberg, Kristen Wiig, and many more, as well as recurring guests such as Alec Baldwin, Melissa McCarthy and Steve Martin. From executive producer Lorne Michaels, "SNL" is widely considered an American late-night institution and continues to earn critical praise.

Improv actor and comic Stephen Colbert flexes the hosting muscles he honed over nearly 1,500 episodes of the popular and critically celebrated "The Colbert Report" at the helm of this long-running late-night talk show. Following the genre's classic formula, each show kicks off with a monologue and a look at recent headlines, and features sketch comedy, celebrity interviews and musical performances. Joining Colbert is his bandleader, Julliard-trained Jon Batiste, and house band Stay Human. The show is filmed in New York's famed Ed Sullivan Theater, the longtime home of "The Late Show."

Broadway, television and film star James Corden takes over the reins of the late-late-night franchise at CBS from fellow U.K. import Craig Ferguson. The British performer -- whose previous hosting gigs include five years of The Brit Awards -- puts his charm, warmth and creative instincts to use as he interviews celebrities and newsmakers, and hosts musical performances in his post-"Late Show" time slot.

An extension of Bravo's "Watch What Happens" reunion specials and the original live online shows, this interactive series -- live on the East Coast -- is hosted by former Bravo programming executive Andy Cohen, who welcomes guests from some of the cable network's most popular series, as well as other entertainment stars, to chat about pop culture and celebrities in the news. In 2017, the show took on a new title -- "Watch What Happens Live With Andy Cohen" -- as part of an overhaul that included a remodeled studio offering a designated performance space for musical guests, a staple of most late-night shows.

The comic, actress, social media sensation, producer and author of "How to Be a Bawse: A Guide to Conquering Life," Lilly Singh brings her unique perspective to late night as she hosts celebrity interviews, talks current events, performs musical and sketch comedy, plays games, and more. A self-proclaimed unicorn, the multi-faceted star's debut in the late-night landscape is especially noteworthy as she's a Canadian woman of Indian descent, combining a fresh take on the day's events, pop culture, diversity and life.
