Show hosts, also known as EMCEES (6 letters) and MCS (3 letters), are people who host or present a show. They are responsible for introducing the performers, keeping the audience entertained, and ensuring that the show runs smoothly. Show hosts often have to think on their feet and be able to improvise in order to keep the show interesting. They must also be able to interact with the audience and make sure that everyone is having a good time.
