Salt Lake Tribune

"The Salt Lake Tribune began as the result of a movement to oppose the political and economic policies of the Mormon Church...The editors replaced their magazine with the new weekly newspaper, which, they stated in their first number, would 'oppose the undue exercise of priestly authority'...In July 1873 three Kansans bought the struggling paper. They escalated the conflict with the Mormon establishment, perhaps reasoning that the way to prosperity lay in a stronger appeal to non-Mormon residents" (Utah History Encyclopedia).
