I found this quite amusing so check it out, do a search query back in google and compare your results from 2001 compared to 2008. The shear volume of number of pages on a search term comparison is nuts.

the usual “dog training”

2001 -Results 1 - 10 of about 926,000 for dog training

2008 - Results 1 - 10 of about 8,770,000 for dog training.

Enjoy!
