In 1982, Buffer began his career as a ring announcer. By 1983, he was announcing all boxing matches promoted by Bob Arum's Top Rank on ESPN, which gave him a national identity at a time when ring announcers were strictly locally hired talent. By 1984, Buffer developed the catchphrase "Let's get ready to rumble" in his announcing, which gained enormous popularity. He began the process of obtaining a federal trademark for the phrase in the 1980s, acquiring it in 1992. Consequently, Buffer has earned in excess of $400 million with the license for his trademark.
