Interesting blog. Relevantly, Jay Leno (part of Baby Boom Generation, born 1942-1953) vs. Conan O’Brien (part of Generation Jones, born 1954-1965) reflects a broader battle happening throughout Western cultures: the emergence of Generation Jones leadership vs. Boomers clinging to power. GenJoneser Obama’s ascendance following 16 years of Boomer Presidencies is the most visible example, but we find it throughout the West, where more than two thirds of EU leaders are part of GenJones (following two decades of Boomer dominance).

Google Generation Jones, and you’ll see it’s gotten lots of media attention, and many prominent commentators from many top publications and networks (Washington Post, Time magazine, NBC, Newsweek, ABC, etc.) now specifically use this term. In fact, the Associated Press’ annual Trend Report chose the Rise of Generation Jones as the #1 trend of 2009. Here’s a page with a good overview of recent media interest in GenJones: http://generationjones.com/2009latest.html

It’s important to distinguish between the post-WWII demographic boom in births vs. the cultural generations born during that era. Generations are a function of the common formative experiences of its members, not the fertility rates of its parents. And most analysts now see generations as getting shorter (usually 10-15 years now), partly because of the acceleration of culture. Many experts now believe it breaks down more or less this way:

DEMOGRAPHIC boom in babies: 1946-1964
Baby Boom GENERATION: 1942-1953
Generation Jones: 1954-1965
Generation X: 1966-1978
