Johnny Carson was among the best known US comedians and television hosts of the 20th century. His signature introduction, “Heeeere’s Johnny” is still fresh in the minds of his audiences. He is best known as the legendary host of the “Tonight Show” on NBC, which he hosted for 30 years. His style was casual and conversational and involved close interaction with the guests.
An appearance on the Tonight Show was considered the ultimate break by the comedians of his time. Many famous US comedians got their break from his show including David Letterman, Jay Leno, Jerry Seinfeld, Ellen, Tim Allen, and Roseanne.
