MC or emcee?

According to Wikipedia, a Master of Ceremonies (MC or compere) is the host of a staged event or similar performance. An MC usually presents performers, speaks to the audience, and generally keeps the event moving. An MC may also tell jokes or anecdotes. The MC sometimes also acts as the protocol officer during an official state function. In hip hop music, rock music and electronic dance music, an MC is a music artist and/or performer who usually creates and performs vocals for his own original material (not to be confused with a DJ who plays party music and creates music mixes). MCs are not limited to rapping; singing is often used in hardstyle and metal music.

According to Dictionary.com, an emcee is a Master of Ceremonies.
