In the Dec. 6 table of contents entry for "America's top philanthropists" (Cover Story), the correct figure for Bill and Melinda Gates' Microsoft Corp. dividend donated to their foundation should be an estimated $3 billion, not $3.35 billion. "The online ad surge" (Web Smart Special Report, Nov. 22), should have credited ad agency Ted Bates & Co., and not its eponymous founder, for the 1980s push toward cable-TV advertising. The review of On Intelligence: How a New Understanding of the Brain Will Lead to the Creation of Truly Intelligent Machines ("Redefining smart," Books, Nov. 8) confused the book's author, Jeff Hawkins, founder of Palm (PLMO
) and Handspring, with Trip Hawkins, game developer and co-founder of Electronic Arts (ERTS
) and founder of 3DO.
