Question: Thomas Edison began serious research into developing a practical incandescent lamp in 1878. Edison filed his first patent application for "Improvement In Electric Lights" on 14 October 1878. After many experiments, first with carbon in the early 1880s and then with platinum and other metals, in the end Edison returned to a carbon filament. The first successful test was on 22 October 1879, and lasted 13.5 hours. Edison continued to improve this design and by 4 November 1879, filed for a US patent for an electric lamp using "a carbon filament or strip coiled and connected ... to platina contact wires." Although the patent described several ways of creating the carbon filament including using "cotton and linen thread, wood splints, papers coiled in various ways," Edison and his team later discovered that a carbonized bamboo filament could last more than 1200 hours. In 1880, the Oregon Railroad and Navigation Company steamer, Columbia, became the first application for Edison's incandescent electric lamps (it was also the first ship to execute use of a dynamo).

Question: In 1996, Turner Broadcasting System merged with Time Warner, which besides placing Turner Classic Movies and Warner Bros. Entertainment under the same corporate umbrella, also gave TCM access to Warner Bros.' library of films released after 1949 (which itself includes other acquired entities such as the Lorimar, Saul Zaentz and National General Pictures libraries); incidentally, TCM had already been running select Warner Bros. film titles through a licensing agreement with the studio that was signed prior to the launch of the channel. In March 1999, MGM paid Warner Bros. and gave up the home video rights to the MGM/UA films owned by Turner to Warner Home Video.

Question: His next theatrical release in that same year was the World War II film Saving Private Ryan, about a group of U.S. soldiers led by Capt. Miller (Tom Hanks) sent to bring home a paratrooper whose three older brothers were killed in the same twenty-four hours, June 56, of the Normandy landing. The film was a huge box office success, grossing over $481 million worldwide and was the biggest film of the year at the North American box office (worldwide it made second place after Michael Bay's Armageddon). Spielberg won his second Academy Award for his direction. The film's graphic, realistic depiction of combat violence influenced later war films such as Black Hawk Down and Enemy at the Gates. The film was also the first major hit for DreamWorks, which co-produced the film with Paramount Pictures (as such, it was Spielberg's first release from the latter that was not part of the Indiana Jones series). Later, Spielberg and Tom Hanks produced a TV mini-series based on Stephen Ambrose's book Band of Brothers. The ten-part HBO mini-series follows Easy Company of the 101st Airborne Division's 506th Parachute Infantry Regiment. The series won a number of awards at the Golden Globes and the Emmys.
