MICROSOFT head and master of the multimedia universe Bill Gates is now spreading his message in that most quaint and old-fashioned of ways -- he's written a book. Buoyed by an excerpt in Newsweek magazine, The Road Ahead, a ''travel guide'' to the future of technology, clicks up seven places to oust shock jock Howard Stern from the nonfiction top spot. There are currently 850,000 copies in print after three pressruns. Oh, and hold on to your mouse, because the book comes with its very own CD-ROM -- of course.
