Gen Y, I mean. That was a typo. And yes, Gen Y did support those shows. Gen Y is now fueling the likes of Supernatural and Heroes. ...And everything Joss Whedon. Gen Yers were '80s babies and '90s kids.
Gen Y seems to like BtVS/AtS more than Firefly, while Gen X prefers Firefly (honestly, I think it's overrated) to BtVS/AtS (massively underrated).
Gen X fuels Lost, House, CSI, NCIS, etc... It's the generation ahead. Well, arguably, House, CSI and NCIS are Baby Boomer shows.
Gen Y were the ones that got Macaulay Culkin, Jonathan Taylor Thomas, Thora Birch, Christina Ricci, the Spice Girls, Britney Spears, '90s pop, Buffy, the Vampire Slayer/Angel: the Series, the rest of the WB shows, The Lord of the Rings, Harry Potter and Pirates of the Caribbean.
Gen Z is fueling Twilight and Hannah Montana.
Though, comically enough, a lot of Baby Boomers like to take credit for the birth of rock'n'roll when it was the generation before them. The Depression/WWII babies were the ones who invented rock'n'roll. The Baby Boomers (post-WWII) created the counterculture '60s and had little in common with the Depression/WWII babies.
Gen X were the kids of the Depression/WWII babies. Gen Y were the kids of the Baby Boomers. Gen Z are the kids of Gen X.
Though, I'm actually a product of a dad who was born the day before Pearl Harbor and a Baby Boomer.
