I was born in 1972. For me that decade has a lot of washed out, faded filmstrip type memories to it. It seems that we saw a filmstrip every day that warned us about playing with fireworks, getting molested, whatever.
I lived in the UK from 1974-1978, and from 1981-1986. My Britain memories are much more vivid. We lived in Florida and West Texas and I just sort of remember school and friends. But culturally, the 1980s were a tidal wave of events. The music, of course. I was too young and too scared to be into punk in 1976, but I remember seeing kids with multicolored mohawks, riots in Brixton, etc. And of course the specter of the cold war - especially being a military brat - was very real, so I thought we’d be blown off the face of the earth by 1988 or so. So for me the pivotal events were:
1976 - Bicentennial (saw that star shaped logo everywhere)
1977 or so - Punk and the Queen’s silver jubilee, lots of protests
1981 - New Romantic music (Duran Duran on the telly every freakin’ day, girls screaming when Simon LeBon opened his mouth)
1982 or so - the docudramas “The Day After” and “Threads” about nuclear war
1984 - The Young Ones, lotsa politics and angry musicians (Paul Weller, Red Wedge, The Smiths)
1986 - Challenger, natch.
1989 - Berlin Wall falling and hope that the world was going to be a safer, more peaceful place. (Oops.)
A kid of the 80s will remember video game mania (Pac Man, Q*bert), Commodore 64s (or crap Atari 800s, BBC Micros, or ZX Spectrums), John Hughes movies, Back to the Future, Indiana Jones, terrible fads like Cabbage Patch kids, cheesy folders with grids to look “futuristic,” Trapper Keepers, old men in the White House (Reagan, Bush), iron ladies on Downing Street, FRANKIE SAY shirts, Rubik’s Cubes, Michael Jackson, Madonna, Prince, We Are The World, Band Aid, Bob Geldof yelling at the telly during LiveAid… that’s just for starters.
Oh - if you were a Black kid in the Southeast US in the late 70s you knew about the Atlanta child abductions and it scared you shitless.
