Generation Y

I've always wondered this myself... now I know.

- People born before 1946 were called The Silent generation.. 
- The Baby Boomers, are people born between 1946 and 1959. 
- Generation X, people have been born between 1960 and 1979. 

- Generation Y , are the people born between 1980 and 2010 
Why do we call the last group Generation Y? 
A cartoonist explained it very eloquently below....

And I always thought it was because they say....

Y should I get a job?
Y should I leave home and find my own place?
Y should I get a car when I can borrow yours?
Y should I clean my room?
Y should I wash and iron my own clothes?
Y should I buy any food?
