Mother Mary Angelica of the Annunciation, commonly known as Mother Angelica, was an American Roman Catholic nun of the Poor Clares of Perpetual Adoration. She was best known for the television show Mother Angelica Live. She was the founder of the international broadcast cable television network Eternal Word Television Network (EWTN) and the radio network WEWN. EWTN became a voice for Catholics worldwide.

The Eternal Word Television Network, more commonly known by its initials EWTN, is an American basic cable television network which presents around-the-clock Catholic-themed programming. It is not only the largest Catholic television network in America, but reportedly "the world's largest religious media network", reaching 425 million people in 160 countries, with 11 networks. It was founded by Mother Angelica, in 1980 and began broadcasting on August 15, 1981, from a garage studio at the Our Lady of the Angels Monastery in Irondale, Alabama, which Mother Angelica founded in 1962. She hosted her own show, Mother Angelica Live, until health issues led to her retirement in September 2001. As of 2017, Michael P. Warsaw, who is a consultant to the Vatican's Dicastery for Communications, leads EWTN.
