Also required, if at all possible:

  • A link to a source (e.g. press release or news story -- the more official the better)
  • Date of acquisition (and announcement if different)
  • Any information on purchase price (even if speculative)

The same question might also apply to other companies, such as Amazon, or Pearson.

on a side note @rgrp: Barbara Van Schewick: "... * A non-discrimination rule that would ban discrimination that causes harm to users or harm to competition. Whether these conditions (anticompetitive, harm to users) are met would be decided by the regulatory agency in case-by-case adjudication. Such a rule was part of the Google-Verizon legislative proposal."

Even if it doesn't seem too active anymore, try Extensive information about Google's acquisitions and investments can be found in this JSON document (licensed CC-BY, license policy).

As for sub-companies of Google, try this OpenCorporates Search.

Very useful and big +1 for the link to the license (though please, if you can, specify which cc-license as some open and some aren't).

Added details to cc-license (it's cc-by in this case).

Thanks for the additions. There's also a CKAN package for crunchbase.

There is a list of acquisitions by Google on WIkipedia: List of acquisitions by Google (you'd have to scrape the table to get the actual "data", such as it is, though...)

Freebase looks like it has some data - e.g. the "child" relation on the Google page appears to point to companies Google owns? []

it is probably incomplete, but you can look at and use the properties dbpedia-owl:subsidiary and dbpedia-owl:owner-of to get an initial list.
