Trinity Broadcasting Network began on May 28, 1973, when Paul and Jan Crouch, together with Jim and Tammy Bakker, who had both previously worked at Pat Robertson's Christian Broadcasting Network, rented air time on a small UHF television station in Santa Ana, California. The founders' own account of the launch describes a single borrowed camera and a shower curtain standing in for a set, airing a few hours of homemade Christian programming a day to a Los Angeles area audience.
The Bakkers left within the year to found their own ministry, PTL, in North Carolina, leaving the Crouches to build TBN as a standalone network. Paul Crouch served as president for four decades, and Jan Crouch remained a visible co-host and network figure until her death in 2016; Paul Crouch had died three years earlier, in 2013. Under their leadership TBN expanded from its single Santa Ana station into a satellite and cable network carried across the United States and, eventually, internationally.
The network's growth from a rented UHF slot to a national broadcaster illustrates a pattern repeated across several religious broadcasting ministries: a preacher or a small team securing a foothold in local broadcasting and using the audience it built to fund a permanent, independent broadcast infrastructure rather than remaining a guest on someone else's program.
