This is a relative question to the previous board about the 60s.

I understand the question, but I think we need to define the context.

In other words wouldn't it be easier to ask what one thing appeared, song, tv show, movie, car, clothing that signaled the '70's were here, or the 60's had passed?

I voted for '72, seemed like we had a lot of stuff on our plate then and it wasn't all about the 60's or hippie stuff either.

Late 72 ...early 73

71 was the real change in autobody styles.

What's diferent for determining the start for the '70s is more of saying "the '60s culture has passed" as opposed to "the '70s culture has arrived". In 1970, you had the Beatles breaking up, Jimmi, Janis, and Jim passing away. Soon, hippie culture passed. The development of '70s culture was very gradual compared to the '80s, '90s, and especially the '60s (July 1963 and February 1964 difference is HUGE!). I'd say in terms of "60s culture vs. 70s culture, it would be something like this":

1969: 95% '60s, 5%  '70s (Brady Bunch/ Jackson 5/Led Zeppelin arrived that fall)
1970: 80% '60s, 20% '70s (Elton John Arrives, 8-tracks are popular)
1971: 65% '60s, 35% '70s
1972: 45% '60s,  55% '70s
1973: 25%  '60s, 75% '70s
1974: 10%  '60s, 90% '70s (First Disco top charters)
1975-76: 100% '70s (Yes, leg warmers were introduced in 1975 and popular by some, but considering it's mid-decade, it doesn't detract from the '70s percentage).
1977: 95% '70s, 5% '80s (Atari 2600, Apple Computer Introduced, first new wave songs)


Whoever voted 1979 as the START of '70s culture needs to read a GOOD BOOK, if anything, I find that year 30% '80s!

1970
