The Incredible Shrinking Wal-mart

I was scanning this Associated Press article that was picked up the the USA Today (Jury orders Wal-Mart to pay at least $78 million for breaking labor laws) and found the oddest discrepancy. In the middle of the article it states: "Wal-Mart is the nation's largest retailer with $10 billion in sales in 2004." It's quite easy to verify that Wal-mart did about $250 billion in 2004 (Wal-Mart tops 1Q target). A strange discrepancy for these two big news organizations, especially since it is such as widely known number. And a typo doesn't make sense here, either. Are reporting standards this lax? I wonder what else I'm hearing in the news these days is wrong.
