> While Google's products do work together I would argue they also work with competitors. I think there are two ways in which it can be argued that Google's auxiliary products destroy competition. On the one hand Google uses its domination in one market (search engines) to subsidize products that end up dominating other markets (online maps, web email etc.). On the other hand these auxiliary products are making it difficult for other search engines to compete with Google. If your search engine has similar (or even slightly better) results to Google, you still have to break into its being the default search engine on the most used web browser and mobile OS, and integrated with maps and other products. If Altavista had been similarly entrenched in 2000, Page and Brin would have likely hit a brick wall despite having a better algorithm. Even Microsoft with all its resources has failed to make a dent in the search space now.
