question:
Question: In what year was the city founded where the WKY Television System is based? Passage:The WKY Television System, based in Oklahoma City and the forerunner to Gaylord Broadcasting, bought the station in 1966 and changed its call letters to WVTV. The new owners also built new studio facilities at the corner of North 35th Street and Capital Drive. This started the station on its path to becoming one of the most popular independent stations in the country, with strong local programming such as The Bowling Game (which would eventually be syndicated across the Midwest), along with a strong slate of syndicated programs such as cartoons, classic off-network sitcoms, more recent sitcoms, drama series, sports, and movies. Like its Gaylord stablemates, channel 18 focused on programming geared towards rural and suburban audiences located in Milwaukee's outer ring, opposed to the more urban fare presented by Milwaukee's other stations. Longtime staples on WVTV included Hee Haw (which was produced by sister division Gaylord Entertainment), The Lawrence Welk Show as well as syndicated reruns of Green Acres and The Andy Griffith Show. The station also aired All Star Wrestling during the 1970s and 1980s.

question:
Question: How far away is the Delaware Canal from the Lehigh Canal? Passage:Sited at the confluence of the rapidly flowing Lehigh River's waters with the more stately waters of the deeper wider Delaware, Easton became a major commercial center during the canal and railroad periods of the 19th century, when it would become a transportation hub for the eastern steel industry. The Delaware Canal, was quickly built soon after the lower Lehigh Canal (1818) became effective in regularly and reliably delivering much needed anthracite coal, into more settled lands along the rivers. And eventually the Morris would also serve to connect the rapidly developing Coal Regions to the north and west, to the fuel starved iron works to the west, the commercial port of Philadelphia to the south, and to the many home owners seeking fuel for heat within Pennsylvania, Maryland, New Jersey, Delaware and New York. Seeing other ways of exploiting the new fuel source, other entrepreneurs quickly moved to connect across the Delaware River reaching into the New York City area to the east via a connection with the Morris Canal in Phillipsburg, New Jersey, so the town became a canal nexus or hub from which the Coal from Mauch Chunk reached the world. The early railroads were often built to parallel and speed shipping along transportation corridors, and by the late 1860s the Lehigh and Susquehanna Railroad (LH&S) and Lehigh Valley Railroad (LVRR) were built to augment the bulk traffic through the canals and provide lucrative passenger travel services. The LVRR, known as 'the Black Diamond Line' would boast the twice daily "Black Diamond Express" daily passenger trains to and from New York City and Buffalo, New York via Easton. The Central Railroad of New Jersey (CNJ), would lease and operate the LH&S tracks from the 1870s until the Conrail consolidations absorbed both the Central Railroad of New Jersey and Lehigh Valley Railroad in 1966. Today, the Lehigh Valley Railroad's main line is the only major rail line that goes through Easton and is now known as the Lehigh Line; the Lehigh Line was bought by the Norfolk Southern Railway in 1999.

answer:
The Delaware Canal, was quickly built soon after the lower Lehigh Canal (1818) became effective in regularly and reliably delivering much needed anthracite coal, into more settled lands along the rivers
