As helper monkeys, we're quite curious. And as a talented, creative individual (who clearly knows where to find great info), we thought you might be curious, too. So we created this infographic (check out the full graphic) to give a look at the mergers, acquisitions, and launches of some of the largest agencies in the world, from the early 1800s to today.
We pulled together tons of agency data for this project from lots of sources across the Web. So if you find something that looks incorrect, please contact the Internet immediately. And if you're an agency who's not on here, but would like to be, let us know in case we get curious enough to try this again.
