Your duties may require you to announce plays, provide commentary, and interview guests. You must have thorough knowledge of the rules, terminology, and history of various sports. Most announcers work in radio and television studios. Some may stay in studio, but many must travel to game sites. You could also be a part-time or self-employed announcer. Expect to work long hours since you may need to be at work before, during, and after games. The median annual wage for announcers as of May 2012 was $28,020, and the job outlook is expected to remain competitive through 2022.
