The station was founded in 1987 and was a 24-hour news station branded as
WSJN 24 Horas, El Canal de Noticias. Some Puerto Rican television reporters started their careers at WSJN, such as
Maria Celeste Arraras, Ada Torres Toro,
Sol Sostre, Nelson Bermejo,
Tony Dandrades, Luis Guardiola, Nellie Rivera, Lyanne Melendez,
Edna Schmidt and Roberto Cortes. In 1993, WSJN-TV returned to the air, and was owned by
El Nuevo Comandante Racetrack corporation, broadcasting Horse racing, and it is branded as
Telenet. On January 13, 1998, WSJN-TV changed its callsign to the current WJPX, after
Paxson Communications purchased the station. On August 31, 1998, WJPX, along with the rest of the Paxson stations, premiered the new
Pax TV television network, with a programming mix of infomercials, off-network reruns labeled as "family entertainment", and
The Worship Network during overnights. WJPX was later sold to
LIN TV in 2000, which affiliated the station with
MTV. At that time, the station broadcast MTV programs (both locally produced and imported from the main MTV network), videos and horse races. The MTV branding and programming were licensed from
Viacom, which, incidentally, once owned two of WJPX's then-sister stations:
WWHO in Columbus, Ohio and
WNDY-TV in Indianapolis, before those stations were sold to LIN in 2005. On October 19, 2006, LIN TV announced that it had entered into an agreement to sell WJPX along with sister station WAPA-TV to
InterMedia Partners for $130 million in cash. The sale was completed on March 30, 2007.
InterMedia Partners then sold the station again to Caribevision Station Group. The sale was completed in October 2007. From March 19, 2009, the subchannel digital 24.2 began transmitting Camarero Racetrack. On August 13, 2012, WJPX began broadcasting
MundoFox; at that time, América Tevé moved to WIRS channel 42.1. On June 15, 2015, MundoFox (which became MundoMax the following month) was moved to channel 24.1 on WKPV in Ponce, WIRS, and WJWN-TV in San Sebastian, while América Tevé moved to channel 42.1 on WJPX, WKPV, and WJWN. WJPX's affiliation with MundoMax ended on August 1, 2016. At that time, the station began to carry América Tevé on channel 24.1. On that same date, WIRS launched a new programming format called Teveo, which is stylized as a 24-hour news channel that airs each weekday from 5 p.m. to midnight and weekends from 7 to 11 p.m. Teveo carries all of the station's live newscasts, along with rebroadcasts of its 6 and 11 p.m. newscasts and its public affairs programs. It also added live weekday hour-long 7 and 9 p.m. newscasts on that date, making it the only station in Puerto Rico with newscasts in those timeslots. On weekends, Teveo carries a "week-in-review" selection of its news programs. Paid programming is shown at other times of the day. On November 12, 2016, WIRS was disaffiliated with Teveo and switched to the
Sonlife Broadcasting Network, a religious television network, owned by televangelist
Jimmy Swaggart, which was seen on
W26DK-D channel 25.2 in San Juan,
W31DL-D channel 36.2 in Ponce and
W51DJ-D channel 51.2 in Mayaguez. ==Technical information==
