Input: Consider Input: Question: What is the location of the headquarters for the company Bremer Broadcasting sold its station to in 1957? Passage:On October 6, 1957, Bremer Broadcasting announced it had sold its stations for $3.5 million to National Telefilm Associates (NTA), an early distributor of motion pictures for television, joining its NTA Film Network. On May 7, 1958, channel 13's call sign was changed to WNTA-TV to reflect the new ownership; the radio stations also adopted these call letters. NTA's cash resources enabled WNTA-TV to produce a schedule of programming with greater emphasis on the people and events of New Jersey, compared to the other commercial television stations. NTA also sought to make channel 13 the center of a new commercial network, though during its run the NTA Film Network offered only one night of "in-pattern" network programming, Friday nights in 1957–58, and for most purposes WNTA served as the New York showcase for nationally syndicated programming and produced several such entries, notably the anthology drama series Play of the Week; the talk show Open End, hosted by David Susskind; children's show The Magic Clown; and a popular dance program emceed by Clay Cole. The station continued to lag behind New York's other independent stations—WNEW-TV (channel 5), WOR-TV (channel 9) and WPIX (channel 11)—in terms of audience size, and NTA incurred a large debt load. National Telefilm Associates put the WNTA stations up for sale in February 1961.

Input: Consider Input: Question: Which wrestler who headlined the Cyber Sunday feud in WWE was born first? Passage:The main feud heading into Cyber Sunday was between WWE Champion John Cena, World Heavyweight Champion King Booker, and ECW World Champion The Big Show, the top champion of each of the three brands. This feud began on the October 9 edition of Raw, where they came face to face, arguing about who was the most dominant champion in WWE. WWE Chairman Vince McMahon interrupted, and booked a triple threat "Champion of Champions" match at Cyber Sunday between the three of them. This also gave each show's General Manager an opportunity to choose opponents for each other's champion that night. This resulted in Big Show defeating Jeff Hardy and Booker defeating Rob Van Dam; however, the match between Cena and The Undertaker was interrupted by Booker, Big Show, and The Undertaker's storyline rival, Mr. Kennedy. At the same time, Cena began a minor feud with Kevin Federline. Federline, as the on-screen close friend of Johnny Nitro and Melina's, appeared on Raw to promote his album, "Playing With Fire". Cena rapped about Federline, but Nitro came out to Federline's defense and was thrown out of the ring by Cena. Cena was then interrupted by his two Cyber Sunday opponents, and McMahon who announced that a championship would be on the line at Cyber Sunday. Cena performed the FU on Federline, after being insulted. The feud between the champions continued on the October 20 edition of SmackDown!, when Big Show and Cena were at ringside during Booker's title defense against Batista. Batista speared Booker onto Big Show, who, in response, assaulted Batista, ending the match via disqualification. Cena then joined the brawl, and SmackDown! General Manager Theodore Long announced a tag team match for the next week. On the next Raw, Cena defeated Nitro after an FU, but was assaulted afterwards by his Cyber Sunday opponents, who turned on each other shortly after to start a brawl between the four to end the show. Batista and Cena were successful in the tag team match, after Big Show abandoned Booker. The next week, on Raw, a preview of Cyber Sunday's interactivity was displayed when fans voted for Cena's opponent for the night, between Big Show, Booker, and Jonathan Coachman. Coachman won in the voting, but was easily defeated by Cena.

Input: Consider Input: Question: How many years was the Las Vegas Hilton called the International Hotel before it was renamed? Passage:In December 1969, Presley called Porter to ask him to fix the sound for him in the main showroom at the International Hotel (renamed the Las Vegas Hilton two years later); he said he could not hear himself the last time he sang there, and a new run was scheduled for January. Porter went to see Presley's first rehearsal there, and found three stage monitors hanging high above the stage, with only one working. The hotel's engineers did not get the other two to work, so Porter had some of his own Shure Vocal Master loudspeakers brought over from the recording studio. He laid the column loudspeakers on their sides at the front lip of the stage and propped them up to aim at Presley, who was very happy with the result. Presley insisted upon having Porter mix his live show in January even though he was a recording engineer with no previous experience in live sound. Porter quickly learned about acoustic feedback during the first song, but backstage after the show, film stars and musical artists kept complimenting Presley, telling him that Porter’s concert sound was "just like the album". Porter mixed Presley's live concerts from then on. Presley paid Porter well for a touring sound engineer; a 1974 contract for nearly two weeks of touring during September–October netted Porter $2,600, an amount equivalent to $ in current value. Porter recorded several of these shows in the mid-1970s, released as albums, and witnessed firsthand Presley's physical decline from drug abuse. In 1975, Presley's doctors advised him to exercise more, so he had a racquetball court built at his mansion Graceland. Porter designed and supervised the installation of a powerful high-fidelity Electro-Voice loudspeaker sound system for the racquetball court and an adjoining lounge. On tour, Porter specified the best-sounding, most roadworthy equipment that existed: he used a Midas PRO4 mixing console and UREI equalizers. The tour was supported by Clair Brothers, who supplied all the audio gear and a monitor engineer, Bruce Jackson, who designed a powerful stage monitor system for Presley's show. In August 1977, Porter was changing planes in Boston to fly to Portland, Maine, to mix a Presley concert when he received a phone call informing him that the singer had died. He attended Presley's heavily guarded funeral ceremony at Graceland. Between Presley appearances, Porter also handled sound duties for Ann-Margret in Las Vegas and on the road, under the business name Captain Audio Productions. He consulted on television specials for Ann-Margret and for Bob Hope in 1972–1973.
