Saturday Night Live (NBC)
Age: 38 seasons.
Senior Power: The highest-rated late-night series on TV. SNL has withstood numerous rivals trying to copy its format over the years and has beaten all of them.
Survival Secret: The Internet excels at delivering short-form video and could have nuked SNL, fueling rivals like College Humor and Funny or Die, along with good ‘ol YouTube. Instead, the web has given SNL shorts a viral boost that extends the life and relevance of each episode.
Life Expectancy: Renewing SNL is probably NBC’s easiest annual decision.
You know we’re going back to CBS for the last one, right?
