COINED: in 1999, as ad execs, fashion houses and Hollywood tried to take the pulse of the lucrative teen market. Generational historians Neil Howe and William Strauss (themselves baby boomers) gave the phrase added currency with their book Millennials Rising: The Next Great Generation Rising.

AVOID CONFUSION: with Generation Y ("As though these kids were a mere Generation X mark II," say Howe and Strauss) or Generation Why? (an even more nihilistic variant of the previous) or Echo Boomers (which apparently suggests these children of the 50s and 60s baby boomers share their parents' rebellious tendencies).

USAGE (descriptive): The Economist 23/12/00: "And they are the 'millennials', with the clean slate and new day that implies: born in the 1980s, the richest generation in history, the best educated, healthiest, the first to grow up knowing nothing of war, famine, disease and poverty."

USAGE (analytical): New York Times 5/11/00: "The Millennials are earnest, can-do types, more like the World War II generation than their parents or older siblings."
