Writer’s block
The famous pilot episode, which aired on September 17, 1972, was actually in just three days. Three days! Crazy. Larry Gelbert wrote the pilot episode and earned a whopping $25,000 for just that ONE episode. Back then, that was considered a lot of money. Gene Reynolds received the Directors Guild of America Award for that episode and it was also nominated for Emmys in Directing and Writing.
11 seasons
Can you believe it but the show actually lasted than the Korean War! The war lasted just over three years while the show was around for 11 seasons, spanning from 1972 until 1983. And did you know that the Writers Guild of America ranked it as the fifth-best written TV series ever while TV Guide ranked it as the eighth-greatest show of all time. I totally agree with that.
