Question: Who is the original broadcaster of The PGA Tour on the network that distributed The Elevator?

full_context: Document 1: Elevator: Some types of residential elevators do not use a traditional elevator shaft, machine room, and elevator hoistway. This allows an elevator to be installed where a traditional elevator may not fit, and simplifies installation. The ASME board first approved machine-room-less systems in a revision of the ASME A17.1 in 2007. Machine-room-less elevators have been available commercially since the mid 1990s, however cost and overall size prevented their adoption to the residential elevator market until around 2010.
Document 2: History of tennis: In 1968, commercial pressures and rumors of some amateurs taking money under the table led to the abandonment of this distinction, inaugurating the open era, in which all players could compete in all tournaments, and top players were able to make their living from tennis. With the beginning of the open era, the establishment of an international professional tennis circuit, and revenues from the sale of television rights, tennis's popularity has spread worldwide, and the sport has shed its upper / middle - class English - speaking image (although it is acknowledged that this stereotype still exists).
Document 3: The Twilight Zone Tower of Terror: On the last word of Serling's narration, the elevator starts its drop sequence. Rather than a simple gravity - powered drop, however, the elevator is pulled downwards, causing most riders to rise off their seats, held down by a seat belt. At least once during the drop sequence, wide elevator doors in front of the riders open to reveal a view of the park from a height of 157 ft (48 m), however the drop is only 130 ft (40 m), the height of a 13 - story building. The elevator drops at a top speed of 39 miles per hour (63 km / h). In the Hollywood Studios version, the back of the ``Hollywood Tower Hotel ''sign partially obstructs the view (the on - ride camera is located here, recording the ride for video or a photograph to be purchased later).
Document 4: The Elevator (1974 film): The Elevator is a made-for-television suspense film that first aired on February 9, 1974 as an ABC Movie of the Week.
Document 5: ESPN College Basketball on ABC: ESPN College Basketball on ABC (originally College Basketball on ABC) is the branding formerly used for broadcasts of NCAA Division I college basketball games produced by ESPN, and televised on the American Broadcasting Company (ABC). ABC broadcast select college basketball games during the 1960s and 1970s, before it began televising them on a regular basis on January 18, 1987 (involving a game between the LSU Tigers and Kentucky Wildcats). As CBS and NBC were also broadcasting college games at the time, this put the sport on all three major broadcast television networks. ABC's final regular college basketball broadcast aired on March 7, 2009 (between the Oklahoma State Cowboys and Oklahoma Sooners).
Document 6: ESPN College Football on ABC: ESPN College Football on ABC (branded for sponsorship purposes as ESPN College Football on ABC presented by Walmart or Kay Jewelers) is the branding used for broadcasts of National Collegiate Athletic Association (NCAA) Division I Football Bowl Subdivision (FBS) college football games that are produced by ESPN, and televised on the American Broadcasting Company (ABC) in the United States. ABC first began broadcasting regular season college football games in 1950 and has aired them on an annual basis since 1966. The network features games from The American, Atlantic Coast, Big Ten, Big 12, and Pac-12 conferences. In addition, ESPN also produces a separate prime time regular-season game package for ABC, under the umbrella brand "Saturday Night Football". (ESPN and ABC are both owned by The Walt Disney Company).
Document 7: Canadian Open (golf): In the mid-1990s, the RCGA decided to move the championship around the country, and continues to alternate between Glen Abbey and other clubs. The owner since 2005, Clublink Corp filed an application in October 2015 to redevelop the property into a residential community, with offices and retail stores. There was no provision for a golf course in the plan. The Town of Oakville Council responded in August 2017 by declaring the golf course a heritage site under the Ontario Heritage Act. This would make it more difficult for ClubLink to develop the area as it had planned. Golf Canada was also concerned since it could not predict whether it could get the necessary permit to hold the Canadian Open at Glen Abbey in 2018 as it had planned. The dispute between the Town of Oakville and ClubLink remains before the provincial appeal tribunal. Due to this situation, the Open will be held at Hamilton Golf and Country Club in 2019.
Document 8: History of tennis: In 1968, commercial pressures and rumors of some amateurs taking money under the table led to the abandonment of this distinction, inaugurating the Open Era (see below), in which all players could compete in all tournaments, and top players were able to make their living from tennis. With the beginning of the open era, the establishment of an international professional tennis circuit, and revenues from the sale of television rights, tennis's popularity has spread worldwide, and the sport has shed its upper / middle - class English - speaking image (although it is acknowledged that this stereotype still exists).
Document 9: Elevator: The Twilight Zone Tower of Terror is the common name for a series of elevator attractions at the Disney's Hollywood Studios park in Orlando, the Disney California Adventure Park park in Anaheim, the Walt Disney Studios Park in Paris and the Tokyo DisneySea park in Tokyo. The central element of this attraction is a simulated free-fall achieved through the use of a high-speed elevator system. For safety reasons, passengers are seated and secured in their seats rather than standing. Unlike most traction elevators, the elevator car and counterweight are joined using a rail system in a continuous loop running through both the top and the bottom of the drop shaft. This allows the drive motor to pull down on the elevator car from underneath, resulting in downward acceleration greater than that of normal gravity. The high-speed drive motor is used to rapidly lift the elevator as well.
Document 10: Elevator: The first elevator shaft preceded the first elevator by four years. Construction for Peter Cooper's Cooper Union Foundation building in New York began in 1853. An elevator shaft was included in the design, because Cooper was confident that a safe passenger elevator would soon be invented. The shaft was cylindrical because Cooper thought it was the most efficient design. Later, Otis designed a special elevator for the building. Today the Otis Elevator Company, now a subsidiary of United Technologies Corporation, is the world's largest manufacturer of vertical transport systems.
Document 11: Men's major golf championships: The majors originally consisted of two British tournaments, The Open Championship and The Amateur Championship, and two American tournaments, the U.S. Open and the U.S. Amateur. With the introduction of the Masters Tournament in 1934, and the rise of professional golf in the late 1940s and 1950s, the term ``major championships ''eventually came to describe the Masters, the U.S. Open, the Open Championship, and the PGA Championship. It is difficult to determine when the definition changed to include the current four tournaments, although many trace it to Arnold Palmer's 1960 season. After winning the Masters and the U.S. Open to start the season, he remarked that if he could win the Open Championship and PGA Championship to finish the season, he would complete`` a grand slam of his own'' to rival Bobby Jones's 1930 feat. Until that time, many U.S. players such as Byron Nelson also considered the Western Open and the North and South Open as two of golf's ``majors, ''and the British PGA Matchplay Championship was as important to British and Commonwealth professionals as the PGA Championship was to Americans.
Document 12: PGA Tour on ABC: PGA Tour on ABC is the "de facto" branding used for telecasts of the main professional golf tournaments of the PGA Tour on the American Broadcasting Company (ABC) television network in the United States. ABC broadcast the PGA Tour from 1966 to 2006. From 1962 to 2009, ABC served as the broadcast home of The Open Championship. The British Open on ABC was the longest-running entertainment program in ABC's history and the last-surviving ABC program to debut in the "circle a" era. ABC also held the broadcast rights of the US Open from 1966 through 1994. and the PGA Championship from 1965 until 1990.
Document 13: Love in an Elevator: The video for the song, considered by many to be a definitive music video for Aerosmith, starts off with the band walking up to a department store elevator, and an attractive woman (Brandi Brandt) says ``2nd floor... hardware, children's wear, lady's lingerie. Oh, good morning Mr. Tyler, going down? ''Steven Tyler enters the elevator and the song starts.
Document 14: NHL on ABC: The NHL on ABC is the branding formerly used for broadcasts of National Hockey League (NHL) games televised on the American Broadcasting Company (ABC) in the United States. The network first broadcast NHL games during the 1992–93 season under a time-buy agreement with ESPN; ABC resumed regular season game telecasts on February 6, 2000, as part of a joint contract with ESPN that also gave ABC the rights to select games from each round of the Stanley Cup playoffs.
Document 15: The Hostage Tower: In the early 1970s, a series of films based on Maclean novels had not performed well at the American box office, including "When Eight Bells Toll", "Puppet on a Chain" and "Fear Is the Key". Maclean decided to focus on American television. He wrote a 120 page novella called "Air Force One is Down" about top executives of various oil companies travelling in Air Force One when it is hijacked. The idea was turned down by NBC. Maclean then pitched a number of new ideas to networks, each with a 25-30 page treatment. "The Hostage Tower" was approved by CBS. The network did request the Eiffel Tower be changed to the Statue of Liberty but Maclean refused, feeling the tower was essential. Filming took six weeks starting in October 1979.
