The generation of children that follows Generation X, whom are people born between the Late 60's to the Early 80's. (1965 to 1980)
Generation Next thereby is anyone born between the Late 80's to Mid 90's. (1980-1995) We are called Generation Next because we are the youth that goes into the Next Millenium and will be the first to have all the advantages of the Jetsons-Like "High Tech" Age, better known as "The Future", where there are robots and flying cars and such, not that much of this will probably be true.
Preceeding "Generation Next" is "Generation Y", the 1995-2010 Youth who I Really feel sorry for. Today, tehy're biggest role models are Lindsay Lohan and Hilary Duff, and they're best childhood cartoon is... Yu-Gi-Oh! (terrible!) Not to mention, they'll be the ones who'll have to fight in the Highly-Anticipated World War III: Rise of the Machines.
