The Onion’s making a push into the online local entertainment markets of ten cities — Madison, Milwaukee, Chicago and Austin already, and Los Angeles, New York, Washington D.C., San Francisco, Denver and the Twin Cities to come, says The Onion’s press release from PR Newswire.

They’re changing the name from AV Club to The Decider. You can see Chicago’s “Decider” site live here. Notice the decider.com domain — why they decided to use a new domain name and not cash in on the existing search-engine cred of theonion.com I have no idea.

So, beside the news that there’s another face in the local-entertainment-guide information game, the other interesting bit (which I heard from a friend of mine) is The Onion is taking all the market-specific articles they’ve published in the AV Club’s archives, and publishing them anew online. The advantage there is that these sites launch with more than just a front page and a handful of articles… also, it’s more information for search engines to index… also, and this is just me thinking out loud, I wonder why other print media with extensive archives don’t take advantage of that gold mine of existing, low-overhead, local information?
