WPXC-TV (channel 21) is a television station licensed to Brunswick, Georgia, United States, broadcasting the Ion Television network to the Jacksonville, Florida, area. It is the only major commercial station in the Jacksonville market that is licensed in Georgia. The station is owned and operated by the Ion Media subsidiary of the E. W. Scripps Company and broadcasts from a transmitter in southwestern Camden County, Georgia, northwest of Kingsland.

Channel 21 began broadcasting as WBSG-TV on April 2, 1990. It was an independent station owned by Coastal Com, Inc., and had studios on Blythe Island Highway (State Route 303) in southwestern Brunswick, as well as a full local news department serving coastal southeastern Georgia. In 1995, WBSG-TV became the nearest affiliate of The WB to Jacksonville. Allbritton Communications purchased WBSG-TV in 1996 and immediately announced it would become the new ABC affiliate for Jacksonville, replacing WJKS-TV. An attempt to move the tower from its original location at Hickox south to Kingsland was delayed, but a height increase allowed the station to put a fringe signal into areas of Jacksonville north of Interstate 10. When WJKS-TV without warning preempted more than half of ABC's prime time shows beginning in January 1997, WJXX (channel 25) was rushed into service to fill the gap. WJXX soon became the primary station in the arrangement; the Brunswick news operation was closed in 1998.

When Allbritton sold WJXX to Gannett in 2000, WBSG-TV was not included. It immediately switched to programming from the Pax network, predecessor to Ion, and was sold outright to the network later that year.

Plans for a commercial television station in Brunswick dated to 1979, when the Federal Communications Commission (FCC) allotted the city channel 21 at the request of COR Communications. COR then applied for the construction permit to build the proposed station. COR Communications was hopeful that their station could attract a national network affiliation. Two other groups—CMM, Inc., and Golden East Broadcasters—also applied for channel 21, and the FCC designated all three applications for comparative hearing in 1983. COR won the construction permit, but its station was never built, and an attempt to replace the construction permit was denied in September 1986.

In December 1986, Richard Huff applied for channel 21 through Coastal Com, Inc. Coastal Com and two other firms' applications were designated for comparative hearing in 1987, and in November, an FCC administrative law judge awarded Coastal Com the permit by summary decision. Coastal Com went public with its plans for WBSG-TV and broke ground on the studios on State Route 303 in August 1989; the station revealed its plans for a news department. The station was envisioned as filling a gap in programming and news coverage that stations in Jacksonville, Florida, and Savannah, Georgia, did not cover.

WBSG-TV began broadcasting on April 2, 1990. It offered news at 6 and 10 p.m. on weeknights and an hour-long local morning show. Because of its distance from Jacksonville and Savannah, the station was able to air some of the same syndicated programs as stations in those markets. WBSG later became an affiliate of The WB; by 1996, it employed 37, including a news staff of nine.

On February 16, 1996, Allbritton Communications announced it had agreed to purchase WBSG-TV from Coastal Com for $10.5 million and that the station would become the new ABC affiliate for the Jacksonville market in 1997 as part of a group affiliation agreement with the network. Allbritton announced it would build new transmitter facilities as well as new studio facilities in Jacksonville in much the same way that WESH served as the NBC affiliate in Orlando despite being nominally licensed to Daytona Beach. The news blindsided Jacksonville's existing ABC affiliate, WJKS-TV (channel 17).

WBSG-TV's existing signal did not reach Jacksonville, so Allbritton filed to build a new tower site near Kingsland. WJKS attempted to block this move by making its own application for a tower in Kingsland, though it retracted this request; the FCC rejected WBSG's Kingsland proposal, leading Allbritton to instead increase the height and power of the existing WBSG-TV facility, though this still left the station unviewable south of Interstate 10. By August 1996, when the FCC approved the upgraded Hickox facility, the affiliation switch had been put off until at least February, and WJKS had given up its fight to remain with ABC. The outright acquisition was converted to a local marketing agreement in August 1996.

Original plans called for WBSG-TV to become Jacksonville's ABC affiliate on April 1, 1997. However, those plans changed in January 1997. With little warning, WJKS started extensive preemptions of ABC programs as part of its transition to become Jacksonville's affiliate of The WB. Of 22 prime time hours offered by ABC, WJKS refused to clear 12+1⁄2 hours as well as any new programs introduced by ABC. This included all of ABC's Sunday and Thursday night programming; the station had already preempted Dangerous Minds on Monday nights and the Saturday night movie. The schedule change was so abrupt that it came after The Florida Times-Union published its weekly television listings; viewers were told to consult the paper's daily program grids instead. Channel 17 continued to broadcast the network's five most popular shows, as well as ABC's network news and soap operas. The uncleared programs were replaced with syndicated shows and programming from The WB. Even though 70 percent of Jacksonville television households subscribed to cable, those that did not and could not receive WBSG-TV were at risk of losing all access to ABC network programming. The scramble to ensure the First Coast would retain access to ABC programming led ABC and Allbritton to agree to accelerate the switch from April 1 to February.

To make up for WBSG's coverage shortfall in the market, Allbritton reached a deal to activate a languishing construction permit licensed to Orange Park, Florida—WYDP (channel 25)—under a local marketing agreement. The compressed timetable forced Allbritton to build an interim facility to provide network coverage to Jacksonville, particularly the southern and western portions of the market. On February 9, 1997, channel 25 came to air as WJXX, and WBSG-TV joined ABC as a semi-satellite. Allbritton later bought WJXX, not WBSG-TV, outright. Allbritton's heavy investment in the combined operation suffered from substantial technical issues caused by the rush to get WJXX on the air. Channel 25 did not have its final technical facilities in place for more than seven months, and it would be another three months before it established a direct feed to area cable systems. Combined with cable channel placement issues in Jacksonville, most of the market's cable subscribers did not get a clear picture from the new station for most of 1997. These issues severely hindered WJXX's competitive position as a Jacksonville station.

The switchover to ABC went far more smoothly for WBSG, though for a time cable providers on the Georgia side of the market reported getting "slightly grainy" reception from channel 21. It simulcast WJXX for most of the day, but maintained its southeast Georgia-focused newscasts at 6 p.m. and 11 p.m. After WJXX launched its Jacksonville-based news department in December 1997, WBSG moved its early evening newscast to 7 p.m. The separate full-length newscasts ended in March 1998, when WBSG was downgraded to a south Georgia bureau for WJXX that placed inserts into WJXX's newscasts. The cutbacks resulted in 11 employees being laid off.

On November 15, 1999, the FCC legalized television station duopolies—the common ownership of two stations in one market. The next day, November 16, the Gannett Company, owner of Jacksonville NBC affiliate WTLV, announced it would purchase WJXX from Allbritton. The deal was initiated after Allbritton approached Gannett about a possible sale. The new duopoly rules barred cross-ownership of two of the top four television stations in the same market, a restriction that typically prevented Big Four network affiliates from coming under common ownership. However, WJXX's fifth-place finish in total-day ratings, somewhat lower than most ABC affiliates, allowed the deal to go forward. The FCC approved the purchase on March 16, 2000, and Gannett took control the next morning. While WJXX and WTLV merged their news departments to form First Coast News, WBSG-TV was not included, and Allbritton converted it to programming from the Pax network. This left some viewers on the Georgia side of the market without access to ABC programming, as WJXX provided marginal-to-nonexistent coverage of south Georgia even after activating its permanent facility. Some cable companies, including those in Brunswick and Waycross, supplemented the area with WJCL in Savannah. That station had been available on some cable systems before Allbritton forced it off the lineup by invoking exclusivity rules.

Paxson Communications Corporation, the owner of the Pax network, purchased WBSG-TV from Allbritton in September 2000. Until that time, the only source of Pax programming in Jacksonville had been a low-power station, WPXJ-LP, operating from a tower in downtown Jacksonville, which Paxson had purchased in 1997 and began broadcasting in 1998. In April 2001, Paxson and WJXT (channel 4) entered into a joint sales agreement by which WJXT sold channel 21's airtime and offered news rebroadcasts on the station. The station changed its call sign to WPXC-TV on July 17, 2001.
