Friday, September 30, 1960, was an incredible night to stay home and watch television. The Twilight Zone kicked off its second season. Rawhide kept "them doggies" rolling with its third season premiere. But in between the two, history was made.

That historic evening, Hanna-Barbera boldly took cartoons where they had never gone before — primetime. In the late 1950s, the animation studio had found early success with The Huckleberry Hound Show and The Quickdraw McGraw Show, two shows aimed at children. The Flintstones was something altogether different and bold — a cartoon aimed at adults.

Today, in a world filled with The Simpsons, Family Guy and Bob's Burgers, we take the idea for granted. In 1960, it was revolutionary. Here was a sitcom with characters, plots and jokes like any other (well, in particular, much like The Honeymooners). The only difference? The episodes were drawn by talented artists.

As the show progressed over its six hit seasons, it slowly veered more into a program aimed at the Boomer youth. Pebbles and Bamm-Bamm were introduced in seasons three and four, respectively. A catch new sing-along theme song was added in season three. Yes, "Meet the Flintstones" did not come along until then! 

This cultural sensation welcomed celebrity guests like Elizabeth Montgomery and Ann-Margret. It spawned cereals, vitamins, toys and countless other collectibles. Now, on its birthday, The Flintstones is back on broadcast television!
