So Google has a monopoly in cash? As I said this is an area to study, not to find 'analogous' situations. The first thing to define in a case is what is the relevant market. You could make the case, and its probably true, that Google has a monopoly in internet text advertising. However, it would be hard to argue that this market is not part of the larger internet advertising market. Microsoft had a straight up desktop monopoly. It was not legal for them to leverage that against another company. I don't know how it matters in the context, but since you brought it up, Netscape didn't give their browser away until 1998. http://en.wikipedia.org/wiki/Netscape http://en.wikipedia.org/wiki/Netscape
