During the 1970s and 1980s, Scottish Television produced a wide range of religious programming including weekly church services, half-hour religious programmes on a Sunday, religious contributions to the new Channel 4, the ever-popular epilogue "Late Call", and occasional documentaries, produced by Executive Producer Rev. Dr Nelson Gray, a Minister of the Congregational Church, and Rev. Eric Hudson, a Minister of the Church of Scotland but as the public service broadcasting requirement receded during the 1990s, the amount of religious programmes were gradually phased out.
