I knew that circulation numbers for newspapers were down, and that ad rates were dropping - but Alan Mutter shows just how bad things are with an inflation adjusted chart (scroll to the bottom after following the link).

As Mathew Ingram notes, online ad sales are not making up the difference - there's just a lot less money being spent there (something like 10% of the amount) - and the click through rates just don't justify an equivalent spend rate. The net is bringing wrenching change to all aspects of media - print, TV, radio, music, movies - you name it, and the comfortable existence of hordes of middle men is vanishing.

That's why you hear all the screaming from the RIAA, the MPAA (et. al.). This kind of change is painful for a lot of people.
