Who or that consortium owns Edison's legacy?

Edison's legacy belongs to three children, and the patent belongs to the company (after General Electric Company).

General Electric Company of the United States is the largest manufacturer of electrical and electronic equipment in the United States and the world, and its output value accounts for about 1/4 of the total output value of the American electrical industry. This electric company was formed in 1892 by the merger of Edison General Electric Company and Thomson-Hausdon International Electric Company funded by Morgan Sr.

In the two world wars, the company made a fortune in the war and achieved rapid development. After World War I, the company was in a dominant position in the emerging field of electronic technology-radio. 19 19 established its subsidiary American radio company, which almost monopolized the radio industry in the United States. The second world war greatly increased the output and profit of General Electric Company.
