An MC usually is a performer who keeps the audience entertained at all times and keeps the event going. The MC sometimes also acts as the protocol officer during an official state function. An MC can be a music artist who usually creates and performs vocals for his/her own original material (not to be confused with a DJ who plays party music and mixes music). Basically, an emcee is the life of the show. Since destination weddings have become a big business these days, the demand for emcees has been increasing.
