WBPX-TV began broadcasting as WQTV in 1979 and originally broadcast subscription television programming to paying customers, which ended in 1983, with the station operating as a full-time commercial independent station until succumbing to financial troubles and paring back its programming. After being sold to The Christian Science Monitor in 1986, WQTV became the nucleus of a major production operation, which in 1991 spawned a cable television channel, the Monitor Channel. After $325 million in losses, this service shut down in 1992, and the Monitor sold WQTV to Boston University, which operated it for six years as commercial independent WABU. Boston University also bought the Concord station, which had been silent since it failed as CBS affiliate WNHT in 1989, and turned it into a satellite of WABU in 1995. Both stations were sold in 1999 to become outlets of the Pax network, which changed its name to i in 2005 before becoming known as Ion in 2007.
