FCC that the sale to Cedar Creek Broadcasting had been terminated. One month after the Cedar Creek purchase's termination (and with the FCC restoring the UHF discount), on June 20, 2017, Ion Media announced that it would purchase WRBU from the Chapman-owned/Ion-managed trust, in a two-station deal with Columbia sister station WZRB, for an undisclosed amount. The sale was completed on October 19, 2017. Technical information Subchannels The station's digital signal is multiplexed: Until May 2014, WRBU transmitted its primary digital channel in 480i standard definition, making it one of the few network-affiliated stations in the United States that did not transmit an HD feed through its digital signal (internal promotions for the station's website and Facebook page that were produced during its MyNetworkTV affiliation were downconverted from 16:9 to a letterboxed 4:3 format when aired on the station). On March 10, 2014, exactly one month after the Chapman/Ion trust took ownership of the station, WRBU began carrying all five subchannel services carried by Ion Media on its Ion Television owned-and-operated stations; it also resulted in WRBU reuniting with HSN's over-the-air service, which Ion has carried on the DT5 feed of its stations since November 2013. On May 1, 2014, WRBU began transmitting its main feed in high definition in the network's standard 720p format. Analog-to-digital conversion WRBU shut down its analog signal, over UHF channel 46, on January 21, 2009. The station's digital signal continued to broadcasts on its pre-transition UHF channel 47. Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 46.
