On Feb. 8, Mary Lou and Gene Dankowski of Minneapolis celebrated a half-century of marriage. The next day, millions of Americans reveled in another 50th anniversary, of the Beatles' first appearance on "The Ed Sullivan Show."
Both commemorations were meaningful, if in entirely different ways.
The Dankowskis can remember that day like it was yesterday, just as so many baby boomers can remember exactly where they were when they watched the Fab Four's U.S. debut.
But in a year awash in 50th anniversaries, many salutes to the events, debuts and inventions of 1964 will not warrant all the hubbub. Arby's, anyone? Acrylic paint? "The Addams Family"? (And those are just the A's.)
There's a reason why we're hearing more about 50-year anniversaries these days. "The boomers were the first generation to ever be marketed to," said Mary Meehan, a consumer and cultural consultant in Minneapolis.
Think about "Mad Men": Cars, toys, fast food, all forms of consumption were being advertised to a postwar generation with money to spend.
Whether any of these anniversaries resonate today depends on the role their debuts played in the culture of the time, Meehan said. "It's tapping into some meaningful values, whether it's humorous or dramatic or indulgent or tragic. Just because it's the 50th anniversary of something doesn't mark it as an icon."
Other factors that matter: timelessness, shared experiences and the nature of our passion. That holds true whether the item or event was hard news or pop culture, a surgeon general's report on smoking or "Dr. Strangelove."
