That's the subject of a new book by Eli Pariser called The Filter Bubble: What the Internet Is Hiding from You. According to Pariser, the internet is increasingly becoming an echo chamber in which websites tailor information according to the preferences they detect in each viewer. Yahoo! News tracks which articles we read. Zappos registers the type of shoes we wear, we prefer. And Netflix stores data on each movie we select. AMY GOODMAN: The top 50 websites collect an average of 64 bits of personal information each time we visit and then custom-designs their sites to conform to our perceived preferences. While these websites profit from tailoring their advertisements to specific visitors, users pay a big price for living in an information bubble outside of their control. Instead of gaining wide exposure to diverse information, we're subjected to narrow online filters. Eli Pariser is the author of The Filter Bubble: What the Internet Is Hiding from You. He is also the board president and former executive director of the group MoveOn.org. Eli joins us in the New York studio right now after a whirlwind tour through the United States.
