In 2018, we’ll be celebrating many significant pop culture anniversaries from “2001: A Space Odyssey” and “Grease” to the arrival of “Sex and the City” and departure of “Seinfeld.” Here’s our annual, extremely subjective list of notable anniversaries — designed, as always, to make you shout out loud, “I can’t believe it’s been that long!”
50th anniversary: On these dates in 1968
"Rowan & Martin’s Laugh-In" premieres
JAN. 22 Fast-paced (for the time) laugh-a-minute hour that revolutionized the sketch-variety show (for the time). Some say presidential candidate Richard Nixon’s September cameo (“Sock it to me?”) helped give him the edge in his neck-and-neck race with Hubert Humphrey. Pictured: Dick Rowan, left, and Dick Martin
Otis Redding's '(Sittin' on) the Dock of the Bay' hits No. 1
MARCH 16 This wistful posthumous hit, recorded three days before his death in a December 1967 plane crash, was the soul singer’s legacy.
'2001: A Space Odyssey' hits theaters
APRIL 6 Stanley Kubrick’s film would break sci-fi barriers. How sad is it that today when we hear its majestic theme song (“Thus Spake Zarathustra”), we first think of the 1970s Elvis waddling on stage. Pictured: Keir Dullea
'60 Minutes' debuts
SEPT. 24 A half-century later, it’s still ticking. Pictured: Mike Wallace in 2002
40th anniversary: On these dates in 1978
“Saturday Night Fever” fever
MAY 13 Yvonne Elliman’s rendition of “If I Can’t Have You,” hit No. 1. In doing so, the movie’s soundtrack album became the first soundtrack to score four No. 1 singles — a record that still stands. The others were three BeeGees’ songs: “Night Fever,” “Stayin’ Alive” and “How Deep Is Your Love.”
'Grease' hits theaters
JUNE 16 The ’50s-set movie (based on the Broadway musical) that millions are still hopelessly devoted to. Pictured: Olivia Newton-John and John Travolta

'Mork & Mindy' premieres
SEPT. 14 “Happy Days” spinoff unleashes a maniac named Robin Williams on an unsuspecting world. Pictured: Pam Dawber and Williams

25th anniversary: On these dates in 1993
Whitney Houston’s “I Will Always Love You" hits No. 1
JAN. 2 Houston’s soaring version of the Dolly Parton song (from “The Bodyguard”) hits No. 1 and will remain atop the charts for nine weeks on its way to becoming an “American Idol” and Karaoke staple.
Billy Joel releases “River of Dreams”
AUG. 10 Who knew at the time that this would be Billy Joel’s last original album? (And who could predict it wouldn’t matter 25 years later when he sells out Madison Square Garden once a month?)
'Late Show with David Letterman' debuts
AUG. 30 The late-night talk-show wars begin as Dave debuts on CBS with Bill Murray, left, and Billy Joel as his first guests.
'NYPD Blue' debuts
SEPT. 21 Groundbreaking cop drama stretched the boundaries of network TV, but, really, did we need to see Dennis Franz’s butt? Pictured: David Caruso, left, Franz, Amy Brenneman, James McDaniel, Sherry Stringfield and Nicholas Turturro
20th anniversary: On these dates in 1998
"Titanic" wins big
MARCH 23 “Titanic” dominates the 70th Academy Awards ceremony. Director James Cameron lets everybody know that he’s “the king of the world!”
MAY 14 The fabled show about “nothing” went out with a one-hour episode in which the four pals end up jailed for violating a small town’s good Samaritan law. Their crime: They did “nothing” to stop a carjacking. Pictured: Michael Richards, left, Jerry Seinfeld, Julia Louis Dreyfuss, Jason Alexander
'Sex and the City' debuts

10th anniversary: On these dates in 2008
“Breaking Bad" debuts
JAN. 20 Before this powerful drama debuted, we just knew Bryan Cranston as a dorky dentist (“Seinfeld”) and a dorky dad (“Malcolm in the Middle.”) Who knew that his dorky chem teacher would evolve into one of TV’s most memorable characters?
Jay-Z and Beyoncé get married
