A month later TomTom, a maker of GPS products, beat out rival Garmin and bought Tele Atlas for $4.2 billion. Were either of these companies really worth that much money? It doesn’t appear like it. Thus concern has been raised that the new owners of the technology might be in a position to hurt competitors by raising prices. We will have to see how things pan out.
