How Much Did Companies Spend on Google Adwords last year and WHY SO MUCH ?!

More companies than you would think, invest over a million dollars a month onGoogle Adwords.  Lowes, Home Depot, Amazon and a few others EACH invested over $50 million with Google Adwords in 2011.  State Farm, Progressive,  Phoenix, AT&T and a couple of others invested over $40 million EACH.  Google’s total revenues for 2011 were $37.9 billion.  Adwords consistently accounts for approximately 97% of Google’s revenues.  Why do these companies continue to pay Google these outrageous sums?  Because they make a lot more than they spend.
