Thomas Alva Edison improved the invention and based his improvements on a patent he purchased from inventors Matthew Evans and Henry Woodward. Edison did, however, develop the first commercially-viable light bulb, which first went on sale in 1880. Woodward and Evans endeavoured to refine and commercialize their light bulb with little success, eventually succumbing to a lack of funding and selling their patent rights to Edison in 1879 for US$5,000 (or about $100,000 in today’s dollars).
