GE

General Electric ("we bring good things to life") was the largest American electrical manufacturer when computing began, but it fumbled its early chances, focusing on other fields like nuclear engineering, factory controls, and jet engines. It made computers in the 1960s, but frequently used systems made by others in its own factories and by the late 1960s had sold its entire division to Honeywell. Computing was not as obvious a growth field then as it is in hindsight, and GE has never caught up or really returned to the field.
