Many religious broadcast networks and stations exist, also surviving on viewer contributions and time leased to the programming producers; the two most prominent are the Trinity Broadcasting Network, which was founded in 1973 by Paul and Jan Crouch as a part-time ministry that leased programming time on KBSA (now UniMás owned-and-operated station KFTR-DT) in the Los Angeles exurb of Ontario, California, before moving to KLXA-TV (now KTBN-TV) in Fontana, which it began purchasing time on in the following year after KBSA was sold; it gradually became the most widely distributed Christian television network in the world with 20 networks (including five in the United States that are primarily available through multicasting, The Church Channel, the youth-oriented JUCE TV and Smile of a Child TV, and the Latino-oriented TBN Enlace USA and TBN Salsa) and several affiliates internationally; and the Daystar Television Network, founded in 1993 by Marcus and Joni Lamb, when the former's Word of God Fellowship ministry purchased the license of defunct UHF station KMPX (now an Estrella TV owned-and-operated station) in Dallas, Texas.
