Much of Google's business depends on pornography. For example, 25% of search engine requests are for pornography.<ref>http://internet-filter-review.toptenreviews.com/internet-pornography-statistics.html</ref>
In addition, although claiming to generally avoid getting involved in matters outside their field, Google officially supports the [[liberal]] and [[social libertarian]] cause of so-called "[[same sex marriage]]."<ref>http://googleblog.blogspot.com/2008/09/our-position-on-californias-no-on-8.html , Our position on California's No on 8 campaign</ref> On June 21, 2009, Google displayed a special multicolored line for searches on the word "gay". More troubling, Google recently announced plans to compensate employees to cover taxes paid on their domestic partner's health benefits, but only offers its 'generosity' to gay couples. <ref>http://www.foxnews.com/scitech/2010/07/01/google-raises-eyebrows-new-gay-employee-benefit/</ref>. Google is also big promoter of [[Charles Darwin]] and atheistic science, even to the point of giving special recognition to the anniversary of Darwin's birthday ("Darwin Day").
Major competitors of Google include [[Yahoo!]] and Microsoft's [[Bing]].
