From Meg Weaver at Wooden Horse Magazine:
"WalMart, the chain that accounts for as much as 40% of many consumer magazine's single copy sales, has just released a new authorized list of magazine titles. It seems WalMart has decided to cut back on the number of magazines they will distribute. The exact numbers of titles involved are still not available but rumor has it that the list has been cut from roughly 3,000 titles to about 1,100...."
Surfing just now, I couldn't locate any new WalMart list of authorized titles, either.
JANUARY 18, 2008 UPDATE: This past Tuesday, Wal-Mart apparently released a list of 1000 magazine titles that it is purging from its shelves; however, I have been unable to find the actual list online. All sources seem to go back to one lone story in the New York Post, written by Keith Kelly, referencing the list and reporting the purge includes such big name titles as Better Homes & Gardens, The New Yorker, The Economist, Business Week, Forbes, and Fortune.
