The term television host can be summarized as an EMCEE, which is a five letter word. An EMCEE is a person who acts as the master of ceremonies at a formal event or show. They are responsible for introducing speakers, performers, and other guests, as well as keeping the event running smoothly. Television hosts are similar to emcees in that they introduce guests and keep the show running on time. They may also provide commentary and ask questions of their guests. Television hosts are often seen on talk shows, game shows, and news programs.
