This is common with companies that want to retain brand recognition while moving away from an outdated image: American Telephone and Telegraph became AT&T, "Kentucky Fried Chicken" became "KFC" to de-emphasize the role of frying in the preparation of its signature dishes, and British Petroleum became BP. "Russia Today" has rebranded itself as "RT". American Movie Classics has simply rebranded itself as AMC. Genzyme Transgenics Corporation became GTC Biotherapeutics, Inc.; The Learning Channel became TLC; and American District Telegraph became simply known as ADT.
