As W22BM and WLBX-LP

A construction permit for UHF channel 22 in Cranford, New Jersey, was granted to Craig Fox with alpha-numeric call-sign W22BM on February 11, 1993; it signed on in March 1997. The call-sign was changed to WLBX-LP on April 24, 1998. WLBX-LP was previously an affiliate of The Box until that network's acquisition by Viacom in 2001; the station then carried MTV2 like many other former Box stations. On September 11, 2001, WLBX-LP aired footage from CNN and TechTV.

As WMBQ

The call sign was changed to WMBQ-CA in 2004. In 2006, Renard Communications Corp. (the Craig Fox-controlled company that by then held the license) began transitioning to a new studio and transmitter they were constructing in Manhattan. Due to this change, WMBQ-CA was displaced from channel 22 to channel 46, and the city of license was changed from Cranford to New York City. On August 17, 2007, Renard Communications Corp. announced that would sell its three stations to Equity Media Holdings for $8 million.^[2] However, the transaction had a closing deadline set for June 1, 2008, and either party could cancel the sale if it were not completed by then. The sale had not been consummated by June 19 of that year, as the company was making budget cuts elsewhere;^[3] and later that year, Equity Media Holdings entered Chapter 11 bankruptcy. On January 3, 2008, WMBQ-CA went dark, reportedly as a result of moving to a new transmitter site.^[4]

In mid-2011, Renard sold WMBQ for $5,250,000 to Prime Time Partners LLC, whose main principals are Jose Rodríguez and Marisol Messir.^[5]

The call sign was changed to WMBQ-CD on April 23, 2012, when the station completed its digital transition. Long-form infomercial programming was added full-time; however, later that year, Canal SOI was added after having been removed from WNJU-DT3, which had aired it for a year. The SOI programming ended in 2013, and infomercial programming was once again added back to the subchannel, with just one local program airing, the morning show Al Día. This format continued through late December; Biz TV was then added, making WMBQ-CD the first station to air financial programming in the New York City TV market since WBIS aired financial programming from 1996 to 1998.

Spectrum sale and donation to WNET

In the Federal Communications Commission (FCC)'s incentive auction, WMBQ-CD sold its spectrum for $28,313,224 and indicated that it would enter into a post-auction channel sharing agreement.^[6] On September 29, 2017, the station entered into a channel sharing agreement with WNET (channel 13); concurrently, Prime Time Partners agreed to donate the WMBQ license to WNET.^[7][8] The donation was completed on December 22, 2017;^[9] the next day, WMBQ-CD was taken off-the-air while WNET prepared to move the shared transmitter to One World Trade Center.^[10] The station returned to the air in November 2018 as an affiliate of MHz Worldview. After MHz Networks announced in January that MHz Worldview would cease operations by March 1, 2020, in favor of digital streaming, WNET switched its programming to First Nations Experience.^[11]
