Generation Y. Why?

• THE SILENT GENERATION people born before 1946.
• THE BABY BOOMERS people born between 1946 and 1959.
• GENERATION X people born between 1960 and 1979.
• GENERATION Y people born between 1980 and 1995.

Why do we call the last one GENERATION Y? I did not know, but a caricaturist explains it eloquently below...
Learned something new!
Hahaha...
