Steve is an antitrust attorney based in Ann Arbor, Michigan, and had a great explanation of antitrust issues in the US and how Google may be a "monopoly" but not a "monopolist."

I invite you to listen in on the conversation over on the Business of Digital podcast website; it's informative and entertaining. You might also wish to subscribe because Mat and Dave share some great information.
