Ever since the 1970's (as far as I can tell) pop culture, music, and fashion from 15-30 years ago has seem to come back into popularity, generally averaged out to the "twenty year rule". Here are just a few examples:
-In the 1970's the 50's came back with the movie "American Graffiti", the "Happy Days" TV show, "American Pie" by Don Mclean about the 50's rock and roll, the "Buddy Holly Story" starring Gary Busey, and Grease. Punk rock which drew on early rock and roll came into fruitation during this decade as well.
-In the 1980's aspects of the 60's came back with films like "Eddie and The Cruisers" and "The Blues Brothers" which brought back Motown, Soul, and Blues of the 1960's. "Back to the Beach" was a straight up retro beach movie starring 60's teen idols Annete Funicello and Frankie Avalon. On top of that the 60's fashion made a comeback as represented in "Pee-wee's Playhouse" and the band the B-52's. Bands like The Beatles and The Doors had a resurgance of popularity during this period.
-In the 1990's the "classic rock" format was created comprising of mostly music from the 1970s. Grunge bands with long hair and a stripped down format came into the mainstream combining elements of influence from Led Zepplin to punk rock. Jam bands had a surge in popularity (Dave Matthews Band?) Punk rock also made a comeback with a new wave of punk bands such as Green Day and Rancid. The 90's saw a "Brady Bunch movie" a TV show based on the 70's "That 70's Show", and a huge resurgance for the "Star Wars trilogy".
-In the 2000's or the "aughts" we saw the resurgance and reunions of bands like The Police, Devo, Oingo Boingo, The Go-Gos, The Pixies. Not to mention new bands using synths again with a clear 80's influence such as The Killers, The Bravery, Peter Bjorn and John, MGMT, Vampire Weekend. Most recently with the death of Michael Jackson, his heyday of the 1980's became as popular as ever. Even spandex came back (as seen on "some" people) do you believe it?!
- While we're just days into the new decade, the 1990's retro movement has already begain in the late aughts with reunions (in some cases "reunions") of Stone Temple Pilots, Alice in Chains, Smashing Pumpkins, Superdrag, The Toadies, and the recently announced reunion of Soundgarden. Haven't you noticed everybody wearing flannel recently?
