List of famous televangelists (also known as "TV evangelists"), with photos where possible. Televangelism is the religious practice in which a Christian Minister largely utilizes television broadcasting to spread his gospel. A televangelist can have his own congregation and church (sometimes large enough to be referred to as a "megachurch"), or he can work solely through television. Television preachers and ministers actually have their roots in radio, later spreading to TV as the technology became available.Who are the most famous televangelists? Popular televangelists have faced great criticism, especially if they act as faith-healers. They have also been accused of greed. This becomes obvious when one compares a televangelist's often opulent lifestyle, especially when compared to traditional men of the cloth: the kind not found on this TV evangelist list.
