Kasem was born in Detroit, Michigan, on April 27, 1932, to Lebanese Druze immigrant parents, who had settled in Michigan, where they worked as grocers. Kasem was named after Turkish leader Mustafa Kemal Ataturk, a man Kasem said his father respected. In the 1940s, "Make Believe Ballroom" reportedly inspired Kasem to follow a career in radio and later host a national radio hits countdown show. Kasem received his first experience in radio covering sports at Northwestern High School in Detroit.
On July 4, 1970, Kasem, along with Don Bustany, Tom Rounds, and Ron Jacobs, launched the weekly radio program American Top 40 (AT40). At the time, top 40 radio was on the decline as DJs preferred to play album-oriented progressive rock. Loosely based on the TV program Your Hit Parade, the show counted down from #40 on the pop charts to #1--the first #1 was Three Dog Night's "Mama Told Me (Not to Come)"--based on the Billboard Hot 100 each week. The show, however, was not just about the countdown. Kasem mixed in biographical information about the artists, flashback, and "long-distance dedication" segments where he read letters written by listeners to dedicate songs of their choice to far away loved ones. He often included trivia facts about songs he played and artists whose work he showcased. Frequently, he mentioned a trivia fact about an unnamed singer before a commercial break, then provided the name of the singer after returning from the break. Kasem ended the program with his signature sign-off, "Keep your feet on the ground and keep reaching for the stars." The show debuted on seven stations, but on the back of Kasem's "always friendly and upbeat" baritone voice it soon went nationwide. In October 1978, the show expanded from three hours a week to four. American Top 40's success spawned several imitators including a weekly half-hour music video television show, America's Top 10, hosted by Kasem himself. "When we first went on the air, I thought we would be around for at least 20 years," he later remarked. "I knew the formula worked. I knew people tuned in to find out what the No. 1 record was." Due to his great knowledge of music, Kasem became known as not just a disc jockey, but also a music historian. In 1971, Kasem provided the character voice of Peter Cottontail in the Rankin/Bass production of Here Comes Peter Cottontail. In the same year, he appeared in the low-budget film The Incredible 2-Headed Transplant, in what was probably his best remembered acting role. From 1973 until 1985, he voiced Robin on several SuperFriends franchise shows. In 1980, he voiced Merry in The Return of the King. He also voiced Alexander Cabot III on Josie and the Pussycats and Josie and the Pussycats in Outer Space, and supplied a number of voices for Sesame Street. In the late 1970s, Kasem portrayed an actor who imitated Columbo in the Hardy Boys/Nancy Drew Mysteries two-part episode "The Mystery of the Hollywood Phantom." He portrayed a golf commentator in an episode of Charlie's Angels titled "Winning is for Losers", and appeared on Police Story, Quincy, M.E., and Switch. In 1977 he was initially hired as the narrator for the ABC sitcom Soap, but quit after the pilot episode due to the content. Rod Roddy took his place on the program. In 1984, Kasem made a cameo in Ghostbusters, reprising his role as the host of American Top 40. For a period in the late 1970s, Kasem was also the staff announcer for the NBC television network.

Were there any spin-offs or other shows similar to the Top 40?

In 1971, Kasem provided the character voice of Peter Cottontail in the Rankin/Bass production of Here Comes Peter Cottontail.

Oscar Leonard Carl Pistorius was born to Henke and Sheila Pistorius on 22 November 1986 in Sandton, Johannesburg, in what was then Transvaal Province (now Gauteng Province) of South Africa. He grew up in a Christian home and has an elder brother, Carl, and a younger sister, Aimee. Pistorius credits his mother, who died at the age of 43 when Pistorius was 15 years old, as a major influence in his life. Pistorius is a white South African with Italian ancestry from his maternal great-grandfather, who was an Italian emigrant to Kenya.
Pistorius has been the subject of criticism because of claims that his artificial limbs give him an advantage over runners with natural ankles and feet. He runs with J-shaped carbon-fibre prosthetics called the "Flex-Foot Cheetah" developed by biomedical engineer Van Phillips and manufactured by Ossur. On 26 March 2007, the IAAF amended its competition rules to include a ban on the use of "any technical device that incorporates springs, wheels or any other element that provides a user with an advantage over another athlete not using such a device". The IAAF stated that the amendment was not specifically aimed at Pistorius. To decide whether he was running with an unfair advantage, the IAAF monitored his track performances using high-definition cameras to film his race against Italian club runners in Rome on 13 July, and his 400 metres in Sheffield on 15 July 2007, at which he placed last. In November 2007, Pistorius was invited to take part in a series of scientific tests at the Cologne Sports University under the guidance of Professor of Biomechanics Dr Peter Bruggemann in conjunction with Elio Locatelli, who was responsible with the IAAF of all technical issues. After two days of tests, Bruggemann reported on his findings on behalf of the IAAF. The report claimed that Pistorius's limbs used 25% less energy than runners with complete natural legs to run at the same speed, and that they led to less vertical motion combined with 30% less mechanical work for lifting the body. In December, Bruggemann told Die Welt newspaper that Pistorius "has considerable advantages over athletes without prosthetic limbs who were tested by us. It was more than just a few percentage points. I did not expect it to be so clear." Based on these findings, on 14 January 2008, the IAAF ruled Pistorius's prostheses ineligible for use in competitions conducted under the IAAF rules, including the 2008 Summer Olympics. Pistorius called the decision "premature and highly subjective" and pledged to continue fighting for his dream. His manager Peet van Zyl said his appeal would be based on advice from United States experts who had said that the report "did not take enough variables into consideration". Pistorius subsequently appealed against the adverse decision to the Court of Arbitration for Sport (CAS) in Lausanne, Switzerland, and appeared before the tribunal at the end of April 2008. After a two-day hearing, on 16 May 2008, the Court of Arbitration for Sport upheld Pistorius's appeal and the IAAF council decision was revoked with immediate effect. The CAS panel unanimously determined that Dr Bruggemann tested Pistorius's biomechanics only at full-speed when he was running in a straight line (unlike a real 400-metre race); that the report did not consider the disadvantages that Pistorius suffers at the start and acceleration phases of the race; and that overall there was no evidence that he had any net advantage over non-disabled athletes. In response to the announcement, Pistorius said: "My focus throughout this appeal has been to ensure that disabled athletes be given the chance to compete and compete fairly with non-disabled athletes. I look forward to continuing my quest to qualify for the Olympics."

What kind of technical device?
any technical device that incorporates springs, wheels or any other element that provides a user with an advantage over another athlete not using such a device".
