The story "Dolby gets ready to make a big noise" (Information Technology, Feb. 9) stated that the technology of Dolby Laboratories Inc.'s chief rival, Digital Theater Systems Inc.

In "Detroit tries it the Japanese way" (Industries, Jan. 26), we incorrectly stated that Joseph Phillippi was president of AutoSource. He is president of AutoTrends Consulting. AutoSource is a different and unrelated company. "Et Cetera..." (In Biz This Week, Mar. 8) contained a typographical error. It should have said that AT&T (T) plans to cut 8% of its workforce in 2004.
