generation to generation

I found this interesting in my Marketing book. I hope it enlarges enough to read when you click on the images.

The generation names leave much to be desired.

NAMES AND BIRTH YEARS:
Tweens: 1996 - 2000
Generation Y: 1977 - 1995
Generation X: 1965 - 1976
Baby Boomers: 1946 - 1964
Seniors: Before 1946
