 Passage 2:Ozii Obiyo (born January 23, 1985) is a Nigerian-American entrepreneur from Arlington, Texas. As a promise to his brother Chuki Obiyo, when they were both students at the University of Texas at Austin, he started the first online African Radio show in Austin, Texas on KVRX called African Extravaganza. Started in 2005, the show showcased a variety of African artists representing different genres and cultures, from Fela Kuti and his Afrobeat to Angelique Kidjo and her Afropop. The fusion of cultures on his show was an experience that Ozii coined as "Afro-fantastic". The radio show led to AfroFantasticTV, a TV show that interviewed students and small business owners on the streets of Austin about African culture through humor. The TV show, broadcast on K09VR, featured Texas business owners discussing how different cultural aspects of Sub-Saharan Africa connected to the Keep Austin Weird business campaign; in one episode, the show featured Mark Cuban, owner of the Dallas Mavericks. As of March 2010, Ozii, through Mediasify, LLC is producing web TV shows, videos, and press releases for business owners.
 Passage 3:Macon was drafted in the second round (twentieth selection) of the 1952 NFL Draft by the Chicago Bears and became the first African-American player on the team; he spent two years as a halfback and return specialist. He was the second African-American to be drafted by the Bears; the first, George Taliaferro, was drafted by them in 1949, but chose to play in the All-America Football Conference. With the Bears, Macon rushed for 324 yards and two touchdowns on 70 attempts while catching 14 passes for 49 yards and two touchdowns. On 22 kick returns, he averaged 30.5 yards per return and 5.9 yards on 24 punt returns. He left the Bears in 1954 to play for the Calgary Stampeders of the Canadian Football League. Bears coach and owner George Halas was not pleased about his departure, blackballing Macon and suing him for $100,000. As a result, the Bears refused to acknowledge Macon being on the team. After being out of football for two years, which he spent as a longshoreman, Macon joined the Hamilton Tiger-Cats in 1957 before leaving in 1959 to resume his longshoreman career, but later joined the Oakland Raiders of the American Football League in 1960. With the Raiders, Macon was converted to defensive back, and was tied for second in the league with nine interceptions, which earned him All-Pro honors.
