He also later worked as a sportscaster for an Ithaca radio station while attending Cornell University, where he obtained a Bachelor of Science degree. At the age of 20, he had begun working for UPI's radio network, which allowed him to cover the 1980 Olympic Games. In 1981, he began working for the newly debuted CNN network as a sportscaster before moving to Los Angeles to work in radio for the next several years. He then returned to television, working as a sportscaster on ESPN from 1992 to 1997.
In 2001, Olbermann returned to CNN, working as a correspondent for "News Night." By this time, he had moved beyond strictly sports programming and had begun reporting on political topics. He received the prestigious Edward R. Murrow award for his coverage of the Sept. 11, 2001, terrorist attacks in New York City.
