• A front-page column on Jan. 19 about the 30th anniversary of the introduction of the Apple Macintosh incorrectly described the location of the building called Bandley 3. The building was near other buildings that at the time made up Apple's campus.

  • Because of incomplete information from the source, the Tech Files column in Monday's Business section incorrectly reported that Flickr charges users who store more than 1 terabyte worth of photos. Flickr offers users an unlimited amount of storage for free. The column also incorrectly reported that Google charges extra to store RAW picture files. Such files count toward a 15-gigabyte limit Google sets on storing collections of certain large files. The company only charges extra to those whose RAW and other large files exceed that limit.
