England is recognized, along with the firm Enterprise Electronics Corporation, as initiating development of the first commercial Doppler weather radar. While the National Weather Service is the only one legally responsible for issuing warnings in the United States, England is credited with issuing the first televised Doppler weather radar bulletin for a tornado, in March 1982. There is a dispute by some sources, as there was an earlier radar bulletin issued by Gil Whitney of WHIO-TV in Dayton, Ohio during the April 3, 1974 Xenia Tornado. However, the radar used by WHIO during the Xenia Tornado was a conventional weather radar, not a Dopplerized radar.
