Its kinda interesting that Google has developed only Gmail as an inhouse product till now !
Similarly, look at Android. Android was purchased very early in their development cycle, and literally grew to a team of hundreds at Google, where the bulk of the work that went into that took place.
This is not to discount that we buy companies because they are doing something interesting/cool/new/smart, but to discount what happens after denies a very large part of how large businesses work.
Maybe what I'm trying to say is if Google can take a legitimate hit when an acquisition goes poorly (dodgeball comes to mind) then maybe it is worth considering what happens when acquisitions come off.
To actually answer your question, gmail, pr, gfs, bigtable, orkut (As a stealthy side project kind of thing), google news, finance, google talk, the igoogle homepage and the gadget spec therein which lead to opensocial, streetview, containerized and large scale data center operations, etc, etc,etc..
But that also discounts the value we've seen from our adoption of open source technologies and the day to day work of thousands of engineers.
Maybe what I'm trying to say is that (ugh, I hate this word) innovation is wherever you find it, and a decent company tries to find it everywhere.
I imagine infrastructure and code can rarely be reused from company to company, so I'm not quite sure what Google gets out of the acquisitions.
Dodgeball and Jaiku are good examples of what you're talking about, though...
Acquisition for a company like Google is smart business. While we don't know the specific dollar amount that Google paid for most of these companies, it was almost certainly less than the cost of than paying Google developers to develop these features from scratch, especially when you factor in the opportunity cost of revenue and traffic lost during the time it takes to develop the product.
AOL?
