The show first appeared in 1968, becoming one of the strongest police dramas in TV history.

With a whopping 12 seasons, "Hawaii Five-0" lasted far longer than most TV shows. Its longevity wouldn't be topped for years.

In 2003, "Law & Order" finally surpassed "Hawaii Five-0" as the longest-running crime drama. The former ran for 20 seasons and 456 episodes.

The show had consistently high rankings that made it a winner for CBS.

The "Five-0" refers to Hawaii's statehood -- the island was the 50th state added to the U.S.

Jack Lord was McGarrett. Lord also had a role as Felix Leiter in the first "James Bond" movie.

McGarrett leads a small team of state police officers who investigate a wide variety of crime scenes.

It won for Outstanding Musical Composition, thanks to the hard work of Morton Stevens.

In the late 60s and early 70s there was very little filming being done in Hawaii, meaning that the locals who were hired to help often had no clue as to what they were supposed to be doing.

McGarrett often uttered the phrase at the end of episodes, in a sign that the team had done its job by catching and jailing the bad guys.

True to the show's name, almost all of the shooting was done on location in Hawaii.

The relaunched series debuted in 2010 and proved successful -- 2016 marked the beginning of the seventh season.

Kalakaua was Zulu, who was a prominent character during the first four seasons of the show.

The wild-eyed Busey was a star of the pilot, and James McArthur returned to play the governor. The pilot never hit broadcast TV.

Richard Boone, who made a name for himself in dozens of Western films, was the first choice, but he turned down the role.

Kokua replaced Kalakaua; Kokua lasted for Seasons 5, 6 and 7.

As the show lasted for more than a decade, the casting director went through five different women who played five secretaries.

Wo Fat is a spy from the People's Republic of China, and he gives McGarrett fits for years.

He'd been a police officer for nearly two decades before he decided to become an actor.

During the 12-season run, the cast and crew managed to churn out 279 episodes.

Fong is the forensic specialist who is trained to examine evidence from a scientific perspective.

Executive producer Leonard Freeman died from heart problems. The rest of the crew had to find a way to fill his considerable shoes for six more seasons.

Actor Kam Fong got tired of the role and wanted to move on with his career. He asked that his character be murdered during an investigation.

Denning gave up the easy life of retirement to play the governor. Denning's career started in 1937 and lasted until at least 1980.

Danno appeared in 11 of the 12 seasons, after which actor James MacArthur went back to his roots in theater.

Carew didn't appear until the 12th and final season. The characters named Truck and Lori Wilson also didn't appear until the 12th season.

One person who watched the episode apparently tried to copy a suicide technique featured in the episode; it was never played again.

Alex O'Loughlin is McGarrett. The actor has also had roles in "Three Rivers" and "Moonlight," among other productions.

His formal suit and tie are unusual in laid-back Hawaii, meaning that McGarrett stands out in a crowd.

Kalakaua, played by Grace Park, is a former professional surfer who gives up the beach bum lifestyle to become a cop.
