Google Panopticonic

The most powerful and protean of these Internet gatekeepers is, of course, Google. With control of 63 percent of the world's Internet searches, as well as ownership of YouTube, Google has enormous influence over who can find an audience on the Web around the world. As an acknowledgment of its power, Google has given Nicole Wong a central role in the company's decision-making process about what controversial user-generated content goes down or stays up on YouTube and other applications owned by Google, including Blogger, the blog site; Picasa, the photo-sharing site; and Orkut, the social networking site.

Wong and her colleagues also oversee Google's search engine: they decide what controversial material does and doesn't appear on the local search engines that Google maintains in many countries in the world, as well as on Google.com. As a result, Wong and her colleagues arguably have more influence over the contours of online expression than anyone else on the planet.
