The post from "goodmamj" is incorrect. This documentary was indeed titled "Light's Diamond Jubilee," not "Light's Golden Jubilee." I can explain why she was confused by the title.
Thomas Edison invented the electric light bulb in 1879. This 1954 documentary was titled "Light's Diamond Jubilee" for the 75th anniversary of the electric light.
Twenty-five years earlier, there had been a prior worldwide celebration termed "Light's Golden Jubilee" to celebrate light's 50th anniversary. In 1929, Edward L. Bernays coordinated the nearly year-long worldwide golden observance of Edison's great technological feat. His efforts were backed by General Electric Corporation.
