Marjorie Costello has been covering consumer electronics for 20 years. Today, she is recognized by her industry and peers as one of the preeminent consumer electronics journalists and analysts. In 1996, Costello launched the Consumer Electronics Online News (CEON), a subscription-based electronic newsletter, where she serves as editor and publisher. CEON is published by Costello Communications, Inc., based in New York.

Costello was also the editor/publisher of ON!, the first non-technical publication about Consumer Electronics, and Video PROphiles, covering prosumer and desktop video.
