Bob Hope's radio shows brought stand-up to the masses

Bob Hope’s 1930s variety shows featured comedic monologues. Unlike the tightly scripted and evergreen sets of vaudeville, Hope’s monologues leaned into topical and political humor, sometimes to the disapproval of his network.

Will Rogers' political humor was an early predecessor to stand-up

Rogers got his start spinning ropes for circus shows and broke through his association with Florence Zeigfeld's Follies and Frolic.

HBO premiered the modern stand-up special in 1975

When they appeared on TV, stand-ups were typically limited to five-minute spots on late-night talk shows, like "The Tonight Show."

Below is a 1959 picture of three more Brill Building pros: Carole King, Paul Simon, and Gerry Goffin.

Mark Twain was an early influence on stand-up

How HBO pioneered the hourlong stand-up comedy special

Stand-up comedy was already on television in the 1970s thanks to Johnny Carson, but comics were limited to clean sets that typically lasted five minutes. HBO, on the other hand, offered stand-ups the opportunity to air their unadulterated material like they would at a club.

Matt Groening wrote the comic 'Life in Hell' before creating 'The Simpsons'

The strip began in 1977 as a self-published book featuring disturbing-looking rabbits navigating the indignities of life in Los Angeles, where Groening had recently moved.

Lenny Bruce's stand-up challenged US law

Longtime director David Silverman and showrunner Matt Selman walk you through some of the show's biggest turning points, from the early days on "The Tracey Ullman Show" through its biggest guest stars and eerily accurate predictions.

Jim Henson and his Muppets were part of the first season of 'Saturday Night Live' because NBC was hoping to tamp down Lorne Michaels' countercultural plans for the show.

Steve Martin and Robin Williams once starred in Samuel Beckett's 'Waiting for Godot,' one of the most well-regarded examples of the existential movement called 'Theater of the Absurd.'

'SNL' spinoffs have had mixed success

As “SNL” became more popular, Lorne Michaels sensed an opportunity to turn some of the show’s most popular sketches and characters into feature films. It’s a strategy that had mixed results: “Wayne’s World” and “The Blues Brothers” are modern classics, while others, like “It’s Pat” and “The Ladies Man,” performed poorly with audiences and critics alike.
