The supermarket is a good example. That's already how it is, all the time, and yet we still get incumbents. Have you seen how many different kinds of jams, jellies, and peanut butters have taken hold? Yes, it's a challenge to be the new guy on the block, but that is just the nature of the beast. Now, if Jiffy paid supermarkets not to stock other brands of peanut butter, that would probably be anti-competitive. If accessing Google cost you money while lycos/yahoo/altavista were free, nobody would have ever tried Google. We can't know for sure, but IMO this is totally not true. The cost for one search worth of traffic is tiny, and their results were superior.
