The hidden rise of personalization on the Internet is controlling--and limiting--the information we consume. In 2009, Google began customizing its search results. Instead of giving you the most broadly popular result, Google now tries to predict what you are most likely to click on. According to MoveOn.org board president Eli Pariser, this change is symptomatic of the most significant shift to take place on the Web in recent years--the rise of personalization. Though the phenomenon has gone largely undetected until now, personalized filters are sweeping the Web, creating individual universes of information for each of us. Data companies track your personal information to sell to advertisers, from your political leanings to the hiking boots you just browsed on Zappos. In a personalized world, we will increasingly be typed and fed only news that is pleasant, familiar, and confirms our beliefs--and because these filters are invisible, we won't know what is being hidden from us. Our past interests will determine what we are exposed to in the future, leaving less room for the unexpected encounters that spark creativity, innovation, and the democratic exchange of ideas.--

Does the information on the Web offer many alternative accounts of reality, or does it subtly align with an official version? In Information Politics on the Web, Richard Rogers identifies the cultures, techniques, and devices that rank and recommend information on the Web, analyzing not only the political content of Web sites but the politics built into the Web's infrastructure. Addressing the larger question of what the Web is for, Rogers argues that the Web is still the best arena for unsettling the official and challenging the familiar.Rogers describes the politics at work on the Web as either back-end--the politics of search engine technology--or front-end--the diversity, inclusivity, and relative prominence of sites publicly accessible on the Web. To analyze this, he developed four "political instruments," or software tools that gather information about the Web by capturing dynamic linking practices, attention cycles for issues, and changing political party commitments. On the basis of his findings on how information politics works, Rogers argues that the Web should be, and can be, a "collision space" for official and unofficial accounts of reality. (One chapter, "The Viagra Files" offers an entertaining analysis of official and unofficial claims for the health benefits of Viagra.) The distinctiveness of the Web as a medium lies partly in the peculiar practices that grant different statuses to information sources. The tools developed by Rogers capture these practices and contribute to the development of a new information politics that takes into account and draws from the competition between the official, the non-governmental, and the underground.
