Amazon.com has launched a beta version of A9, its entry into the search engine market. “A9.com, an independent unit of the Internet retailer, unveiled its Web site on Wednesday after nearly seven months of development,” reports CNET News.com. “The search site touts a novel design that lets people sift through Web search results, store and view their own search history, and find book information from Amazon related to query terms. It also promotes a search toolbar that blocks pop-up ads.”
