Once, a generation was called "us." Or "them." Maybe "the grownups." Or "kids these days" — if, indeed, anyone ever gave a passing thought to lumping together people with nothing more in common than an age span.
Then in January of 1970, a story in the Washington Post used the term "baby boomer" to describe Americans born between 1946 and 1964, a period that long had been called the "baby boom" spawned by the postwar prosperity.
The moniker caught fire, and cultural shorthand would never be the same.
Consider the images that come to mind for the term "millennial" (twentysomethings struggling to land jobs in their degree fields) or "Generation X" (parents living in their SUVs while trundling between their kids' activities) or "Greatest Generation" (anyone in a retirement home).
The brushstrokes may be broad, but such terms both define and target each generation. Little wonder, then, that naming rights for the upcoming group already are being claimed.
The buzz is driven in part by a new book by Paul Taylor with the Pew Research Center, that insatiable collector of public opinion. In "The Next America: Boomers, Millennials, and the Looming Generational Showdown," Taylor argues that shifts in demographics, economics, culture and technology are reshaping how generations regard each other.
In a recent appearance on Jon Stewart's "The Daily Show," Taylor was asked what he'd call the upcoming generation. He said he didn't yet know.
Responded Stewart: "You just opened up a contest, my friend."
