In 1965 the animated holiday special, "A Charlie Brown Christmas" first aired on television.
ABC will be celebrating the golden anniversary by airing the show Monday at 9 p.m., along with an additional feature entitled "It's your 50th Christmas Charlie Brown" with host Kristen Bell at 8 p.m.
These days, it's hard to think of "A Charlie Brown Christmas" as anything less than a holiday classic, but according to Lee Mendelson, who produced the special along with Peanuts creator Charles Schulz and director Bill Melendez, no one expected that it would ever get the amount of attention that it did.
"I thought we had ruined Charlie Brown," Melendes says. "The network didn't like it either. They thought it was too slow. We thought it was going to be a one time and out."
Their doubts couldn't have been more wrong.
Mendelson's relationship with Schulz began when he called him up with the idea to create a documentary about the Peanuts comic strip. The finished documentary attracted the attention of a certain popular brand.
"Coca-Cola called," Mendelson recalls. "They had seen our documentary and liked it and they said, 'Have you folks ever thought about doing a Christmas show?' and I said, 'Absolutely!'"
All that was left was to get Schulz on board with the idea.
"I called Mr. Schulz and I said, 'I think I just sold A Charlie Brown Christmas.' and he said, 'What in the world is that?' and I said 'That's something you're going to write tomorrow!'"
The production was a major risk. In addition to having children voice the main characters, Mendelson decided to have jazz-musician Vince Guaraldi create the music.
He knew it was the right decision the first time he heard Guaraldi play the classic song, "Linus and Lucy."
"I remember saying this is going to change Vince's life and my life," Mendelson says. "Why I thought that, I have no idea."
"A Charlie Brown Christmas" is full of moments that have resonated with audiences. Mendelson says that his personal favorite comes when Linus wraps his blanket around Charlie Brown's scrawny little tree.
"[Linus] says, 'All it needs is a little love.' That's always the line that I remember the most" Mendelson says. "I thought that particular line was very very important."
