>>1007957362003-2004 was the last true Gen Y kid culture year. It was the last time you had Rocket power, Snick, Cartoon Cartoon fridays, Johnny bravo, Frasier, friends, Samurai jack, Rugrats, Hey arnold, pre-movie Spongebob, pre-channel chasers Fairly odd parents, Pokemon when Misty was there, Dexter's lab, etc., the last Web 1.0 year, the last time where VHS, Discmans, CRTs, Gameboy colors, payphones, Bop It's, Tamagotchis, Furbys, Robodogs, Super Soakers, etc. were firmly popular, the last year where Pop Punk, Nu Metal, and R&B had an early 2000s style, baggy jeans were fashionable with guys, stores like Old Navy were still relevant, online gaming not system seller and local multiplayer still very common, etc.
The 2004-2006 school years were truly transitional years between Gen Y and Gen Z culture and 2006-2007 was probably the first true Gen Z kid Culture Year, when you had Hannah Montana, the Wii, High School Musical, Chowder, Flapjack, Cartoon network making live action shows, cancellation of Malcolm in the middle and Yu yu hakusho, death of Steve irwin, really fast internet, HDTV, etc. Maybe that's the reason why a lot of us stopped watching kid channels in or around this time
