Macworld and the giant Consumer Electronics Show (CES) will take place at the same time next year.
Apple's event takes place between January 8-12, while CES 2007 runs January 8-11.
CES shifted its date because of its contract with its Las Vegas venue, reports say.
A Macworld Expo spokesperson said: "We've always had our event in the second week of January, beginning on Monday. They're the ones who changed the date."
