Stereophonic sound recording, which attempts to provide a more natural listening experience by reproducing the spatial locations of sound sources in the horizontal plane, was the natural extension to monophonic recording, and attracted various alternative engineering attempts. The ultimately dominant "45/45" stereophonic record system was invented by Alan Blumlein of EMI in 1931 and patented the same year. EMI cut the first stereo test discs using the system in 1933 (see Bell Labs Stereo Experiments of 1933) although the system was not exploited commercially until much later.
When did EMI create the first stereo discs?
****
The answer: 1933

 South Korea: The event was held in Seoul, which hosted the 1988 Summer Olympics, on April 27. Intended torchbearers Choi Seung-kook and Park Won-sun boycotted the event to protest against the Chinese government's crackdown in Tibet. More than 8,000 riot police were deployed to guard the 24-kilometre route, which began at Olympic Park, which was built when Seoul hosted the 1988 Summer Games. On the day of the torch relay in Seoul, Chinese students clashed with protesters, throwing rocks, bottles, and punches. A North Korean defector whose brother defected to China but was captured and executed by the DPRK, attempted to set himself on fire in protest of China's treatment of North Korean refugees. He poured gasoline on himself but police quickly surrounded him and carried him away. Two other demonstrators tried to storm the torch but failed. Fighting broke out near the beginning of the relay between a group of 500 Chinese supporters and approximately 50 protesters who carried a banner that read: "Free North Korean refugees in China." The students threw stones and water bottles as approximately 2,500 police tried to keep the groups separated. Police said they arrested five people, including a Chinese student who was arrested for allegedly throwing rocks. Thousands of Chinese followed the torch on its 4.5 hour journey, some chanting, "Go China, go Olympics!" By the end of the relay, Chinese students became violent, and it was reported in Korean media that they were "lynching" everyone who was disagreeing with them. One police man was also rushed to hospital after being attacked by Chinese students. On Apr 29, the Secretary of Justice, Kim Kyung Han, told the prime minister that he will find "every single Chinese who was involved and bring them to justice." Later in the day, South Korea's Prosecutor's Office, National Police Agency, Ministry of Foreign Affairs and National Intelligence Service made a joint statement saying that they will be deporting every Chinese student that was involved in the incident. China defended the conduct of the students.
Where was the torch relay event held in South Korea?

According to the Namibia Labour Force Survey Report 2012, conducted by the Namibia Statistics Agency, the country's unemployment rate is 27.4%. "Strict unemployment" (people actively seeking a full-time job) stood at 20.2% in 2000, 21.9% in 2004 and spiraled to 29.4% in 2008. Under a broader definition (including people that have given up searching for employment) unemployment rose to 36.7% in 2004. This estimate considers people in the informal economy as employed. Labour and Social Welfare Minister Immanuel Ngatjizeko praised the 2008 study as "by far superior in scope and quality to any that has been available previously", but its methodology has also received criticism.
