Go back to the beginning of television's longest-running primetime drama with behind-the-scenes footage, memorable scenes and exclusive interviews with the actors, creators and crew members.

The top 40 funniest cartoon characters are showcased in this TV special, as determined by a Nielsen viewers' survey.

Celebrating the holiday season with a one-hour television event where viewers can enjoy the Grammy Award-winning musical phenomenon Pentatonix performing an array of classic holiday tracks as well as modern favorites.

From "The Golden Girls" to "The Good Place," from "The Rockford Files" to "This Is Us," from Jack, to Johnny, to Jay, to Jimmy, the rich and prolific history of NBC is celebrated. Five-time Emmy Award winner Kelsey Grammer will serve as host. Grammer is, of course, best known in television history as Frasier Crane, who was first introduced on NBC on "Wings" before moving on to "Cheers" and then "Frasier" - tying the record for the longest-running (non-animated) character on television at 20 years with James Arness from "Gunsmoke."
