Finally, in 1930, farnsworth received a patent for the first electronic television: after the company"s court defeat, rca"s president, david sarnoff, had to negotiate to use. Setting technical standards: figuring out how to push tv as a business and elevate it to a mass medium meant creating a coherent set of technical standards for product manufacturers.
