Question: How many years had the Nexstar Broadcasting Group been in business at the time of their purchase of KSEE assets? Passage 1:The Anzac class originated from RAN plans to replace the six River-class destroyer escorts with a mid-capability patrol frigate. The Australian shipbuilding industry was thought to be incapable of warship design, so the RAN decided to take a proven foreign design and modify it. Around the same time, the Royal New Zealand Navy (RNZN) was looking to replace four Leander-class frigates; a deterioration in New Zealand-United States relations, the need to improve alliances with nearby nations, and the commonalities between the RAN and RNZN ships' requirements led the two nations to begin collaborating on the acquisition in 1987. Tenders were requested by the Anzac Ship Project at the end of 1986, with 12 ship designs (including an airship) submitted. By August 1987, the tenders were narrowed down in October to Blohm + Voss's MEKO 200 design, the M class (later Karel Doorman class) offered by Royal Schelde, and a scaled-down Type 23 frigate proposed by Yarrow Shipbuilders. In 1989, the Australian government announced that Melbourne-based shipbuilder AMECON (which became Tenix Defense) would build the modified MEKO 200 design. The Australians ordered eight ships, while New Zealand ordered two, with an unexercised option for two more.
 Passage 2:Following the defeat of Arab armies in the 1948 Palestine war, the Arab world went into an era of political assassinations and military coups that culminated in the Egyptian Revolution of 1952, which brought Gamal Abdel Nasser into the leadership of Egypt. Nasser's ascend to power was a turning point in the history of the region and the revolutionary wave had spread to Algeria, Bahrain, Iraq, Yemen and Libya. This wave however faced a historic defeat in the 1967 Arab–Israeli War. The author states that this defeat was worse than that of 1948 and had signaled the end of the Nasserite revolutionary wave, which was replaced by the Islamist wave. This wave reached its climax in early 1980s after the Islamic Revolution in Iran and Soviet invasion of Afghanistan, which turned Afghanistan into a hub for Mujahideen. The Arab revolutions that succeeded did not bring al-Nadha nor freedom, instead they had turned into authoritarian regimes. These developments and the 8-year Iran–Iraq War have struck a fatal blow to the Arab revolutionary wave of hope.
 Passage 3:On February 6, 2013, Granite sold KSEE's non-license assets to the Nexstar Broadcasting Group, with Nexstar also intending to purchase KSEE's license following Federal Communications Commission approval; in the interim, Nexstar operated the station via a time brokerage agreement. The deal made KSEE a sister station to CBS affiliate KGPE, which Nexstar had just acquired from Newport Television. Normally, duopolies between two "Big Four" affiliates, let alone "Big Three," would not be allowed because those stations are usually the four highest-rated stations in a market, which FCC regulations do not allow any common ownership of. However, according to Nielsen, in 2013 KGPE was ranked as the fourth highest-rated station in the market and KSEE fifth, after KFSN (ABC), KFTV (Univision), and KMPH-TV (Fox), allowing a duopoly to be formed between the stations. This marked the second instance (after the Gannett Company purchased ABC affiliate WJXX in Jacksonville, Florida, creating a duopoly with that market's NBC affiliate WTLV, in 2000) in which a single company owns a duopoly involving two stations that are affiliated by a Big Three television network; and is also Nexstar's first true Big Three duopoly (Nexstar's other Big Three duopolies are virtually formed, in which the other station is owned by Mission Broadcasting). The merger was approved on April 17, and completed by May 31.
