Sylvania Electric Products Inc. was an East Coast American manufacturer of electrical and electronic equipment, including at various times incandescent light bulbs, vacuum tubes, fluorescent lamps, radio transmitters and receivers, customer-specified devices, cathode ray tubes and television sets, semiconductors and integrated circuits, and mainframe computers such as MOBIDIC. They were one of the companies involved in the development of the COBOL programming language.

The company was an innovator and through its research department obtained hundreds of patents. Among the innovations was the first commercially relevant line of TTL logic integrated circuits.

The company history can be traced back to 1901, when Frank A. Poor, a merchant in agriculture products from Salem, Massachusetts, partnered up to start a small business refilling burned-out light bulbs.
