The lawyers and executives over at Google must be very aware of the antitrust problems they face, but then again I am sure that the people at AT&T were similarly aware before they were forced to break up the company. If they need any insights perhaps they can go through Google Books and find Ray G. Besing's book "Who Broke Up AT&T".
Google is not helping themselves with recent moves, like the purchase of AdMob announced this week and their intention of providing free GPS software.
The question is has Google gotten so big that growth activity has swamped their executives and they are too busy to think about the possibility of serious antitrust problems. Or are they just too confident that it will not happen to them. Has success blinded them?
AT&T's biggest factor in being broken up was "was using monopoly profits from its Western Electric subsidiary to subsidize the costs of its network, which was contrary to U.S. antitrust law," as Wikipedia notes.
Obviously Google is using profits from other areas to provide free services to internet users and website owners. Google Analytics is a good example, and would be interesting if someone remaining in the space were to challenge them.
Interestingly, AT&T is pushing the FCC to look in to Google's activities with their new Voice product. Meanwhile, the EU has been investigating Google Books and recently added a complaint from Italian newspaper publishers who claim they are being removed from regular search results because they decided not to be included in Google News.
In the US, the actions of AdWords creating minimum bids and use of Quality Scores etc. to justify huge increases in the cost per click for keywords has been voiced by many in the space, but a suit by TradeComet may add to the momentum of antitrust actions against Google. TradeComet had been buying clicks from hundreds of thousands of keywords to drive traffic to their SourceTool site, but "the complaint states, Google raised the price SourceTool had to pay for many keywords 100-fold (from 10¢ a word, for example, to $10). In a short time, TradeComet alleges, SourceTool lost 90% of its monthly traffic from Google and millions of dollars in revenue," BusinessWeek reported.
The video below of Dana R. Wagner, Google's top in-house antitrust lawyer shows they are aware of their situation.
