A question increasingly asked is whether Google is becoming a dangerous monopoly. It is a very serious question. If we end up with one company controlling search - the gateway to information - it could be catastrophic if it abused its position. Google is already technically a monopoly with nearly 70% of US search and as much as 90% in the UK on some surveys. But it is highly unusual for two reasons. First, it lacks the typical symptom - charging excessively for its products. Nearly all of Google's products from search to document storage are free. What kind of monopoly is that?
