American inventor who transmitted the first all-electronic television image in his San Francisco laboratory in 1927, using his image dissector camera tube. Electronic scanning, not spinning discs, is the principle every later television system used, and Farnsworth fought and won a long patent battle with RCA over its paternity.

Baird demonstrated a mechanical scanning system, a spinning disc, in 1926. Farnsworth developed a separate all-electronic system built around his own image dissector camera tube. The two are different technical lineages toward the same goal, not sequential steps in one invention; the Baird Company itself later licensed Farnsworths image dissector and found it inferior to the rival Emitron tube.

The Baird Company had a sharing agreement with the American inventor of electric television, Philo T Farnsworth, that allowed them to use his image dissector; the tube was inferior to the Emitron and required huge amounts of light.
