Google Viewer: I'm Not Seeing It
The idea behind the Google Viewer software program was that you could type in a query, press submit, and then sit back and watch as it loaded actual Web pages that it found. Next, Google Viewer displayed the results to you as a slide show. The program, which PC World reported on in 2002, was eventually abandoned.
The idea of sneaking a peak at a Web page before clicking on the link eventually came to fruition--it just didn't require a software download to do it. Today you can preview pages in search results delivered by Ask.com, Powerset, and Yahoo, no application required.
