Newsosaur Alan Mutter noticed that the Newspaper Association of America released their final 2011 ad revenue numbers Wednesday, and you won’t be surprised to learn they’re not good. The headlines:

— Ad revenues (print + online) are less than half what they were in 2005 ($49.4 billion vs. $23.9 billion).

— Online ad revenues were up in 2011, but only 6.8 percent from 2010. Newspapers still earn $6.36 in print ad revenue for every $1 in digital ad revenue.

— Mutter notes that the last time newspaper ad revenue was this low was in 1984. But it’s even worse when you take inflation into account.

The last year newspaper ad revenues were this low in real dollars was in 1954. That year, the newspaper business earned just under $2.7 billion — which in 2011 dollars would be around $22.5 billion.
