MacWEEK was a controlled-circulation weekly Apple Macintosh trade journal based in San Francisco founded by Michael Tchong, John Anderson, Glenn Patch, Dick Govatski, and Michael F. Billings. It featured a back-page rumor column penned by the pseudonymous Mac the Knife.Founded in 1987, it was acquired by Ziff-Davis in 1988. In 1998, as part of a strategy change, the print publication was relaunched as eMediaWeekly, which caused a number of its existing sponsors to withhold their advertising.
