Background: John Logie Baird FRSE (; 13 August 1888 - 14 June 1946) was a Scottish engineer, innovator, one of the inventors of the mechanical television, demonstrating the first working television system on 26 January 1926, and inventor of both the first publicly demonstrated colour television system, and the first purely electronic colour television picture tube. In 1928 the Baird Television Development Company achieved the first transatlantic television transmission. Baird's early technological successes and his role in the practical introduction of broadcast television for home entertainment have earned him a prominent place in television's history.
Context: Baird made many contributions to the field of electronic television after mechanical systems had taken a back seat. In 1939, he showed a system known today as hybrid colour using a cathode ray tube in front of which revolved a disc fitted with colour filters, a method taken up by CBS and RCA in the United States.  As early as 1940, Baird had started work on a fully electronic system he called the "Telechrome". Early Telechrome devices used two electron guns aimed at either side of a phosphor plate. The phosphor was patterned so the electrons from the guns only fell on one side of the patterning or the other. Using cyan and magenta phosphors, a reasonable limited-colour image could be obtained. He also demonstrated the same system using monochrome signals to produce a 3D image (called "stereoscopic" at the time). In 1941, he patented and demonstrated this system of three-dimensional television at a definition of 500 lines. On 16 August 1944, he gave the world's first demonstration of a practical fully electronic colour television display. His 600-line colour system used triple interlacing, using six scans to build each picture. Similar concepts were common through the 1940s and 50s, differing primarily in the way they re-combined the colours generated by the three guns. One of them, the Geer tube, was similar to Baird's concept, but used small pyramids with the phosphors deposited on their outside faces, instead of Baird's 3D patterning on a flat surface.  In 1943, the Hankey Committee was appointed to oversee the resumption of television broadcasts after the war. Baird persuaded them to make plans to adopt his proposed 1000-line Telechrome electronic colour system as the new post-war broadcast standard. The picture resolution on this system would have been comparable to today's HDTV (High Definition Television). The Hankey Committee's plan lost all momentum partly due to the challenges of postwar reconstruction. The monochrome 405-line standard remained in place until 1985 in some areas, and the 625-line system was introduced in 1964 and (PAL) colour in 1967. A demonstration of large screen three-dimensional television by the BBC was reported in March 2008, over 60 years after Baird's demonstration.

Background: The North American fur trade was the industry and activities related to the acquisition, trade, exchange, and sale of animal furs in North America. Aboriginal peoples in Canada and Native Americans in the United States of different regions traded among themselves in the Pre-Columbian Era, but Europeans participated in the trade beginning from the time of their arrival in the New World and extended its reach to Europe. The French started trading in the 16th century, the English established trading posts on Hudson Bay in present-day Canada in the 17th century, and the Dutch had trade by the same time in New Netherland. The 19th-century North American fur trade, when the industry was at its peak of economic importance, involved the development of elaborate trade networks.
Context: Deerskin trade was at its most profitable in the mid-18th century. The Creeks rose up as the largest deerskin supplier, and the increase in supply only intensified European demand for deerskins. Native Americans continued to negotiate the most lucrative trade deals by forcing England, France, and Spain to compete for their supply of deerskins. In the 1750s and 1760s, the Seven Years' War disrupted France's ability to provide manufactures goods to its allies, the Choctaws and Chickasaw. The French and Indian War further disrupted trade, as the British blockaded French goods. The Cherokees allied themselves with France, who were driven out from the southeast in accordance with the Treaty of Paris in 1763. The British were now the dominant trading power in the southeast.  While both the Cherokee and the Creek were the main trading partners of the British, their relationships with the British were different. The Creeks adapted to the new economic trade system, and managed to hold onto their old social structures. Originally Cherokee land was divided into five districts; however, the number soon grew to thirteen districts with 200 hunters assigned per district due to deerskin demand.  Charleston and Savannah were the main trading ports for the export of deerskins. Deerskins became the most popular export, and monetarily supported the colonies with the revenue produced by taxes on deerskins. Charleston's trade was regulated by the Indian Trade Commission, composed of traders who monopolized the market and profited off the sale of deerskins. From the beginning of the 18th century to mid-century, the deerskin exports of Charleston more than doubled in exports. Charleston received tobacco and sugar from the West Indies and rum from the North in exchange for deerskins. In return for deerskins, Great Britain sent woolens, guns, ammunition, iron tools, clothing, and other manufactured goods that were traded to the Native Americans.
