The folks over at The Awl have taken Audit Bureau of Circulation numbers for six major papers and made an interesting graph showing circulation rates since 1990. The New York post has returned to it's 1990 numbers while the Los Angeles Times has seen a rapid decline. I was working for the Times during some of the major layoffs. Soon after I left the national bureau faced several hard cuts and lost many dedicated, hard working and talented reporters.
