Watch Wal-Mart Spread Like a Virus

Wal-Mart started as a single discount store in Arkansas in 1962. Today there are roughly a gazillion Wal-Marts covering basically the entire planet.

Now, thanks to author and geek Toby Segaran, you can watch Wal-Mart spread across the U.S. like a virus.

Thanks, Bill.

It's hard to remember what the world was like before Wal-Mart...
