Enterprise Electronics improved the commercial Doppler prototype, and in 1991, KWTV purchased the Doppler 9000XL, which included a computer that interpreted the reams of data. After using the computer for a while, Gary convinced KWTV to hire a software programmer to write a program that would estimate a storm’s time of arrival for each city and town in the state. KWTV called the system Storm Tracker, modified it to fit all fifty states, and sold it around the country.
