The station formally signed on the air as WWSI on January 17, 2001, originally licensed to Atlantic City, New Jersey, with transmitter in Waterford Township. It acquired the Telemundo affiliation for the Philadelphia market (originally seen on Wilmington, Delaware-based WTGI—channel 61, now Ion Television owned-and-operated station WPPX-TV—until 1998, then WTVE—channel 51—in Reading, Pennsylvania from 1998 to 2000). WWSI launched its website in 2007. In January 2008, Hispanic Broadcasters Corporation agreed to sell WWSI to ZGS Communications for $10 million. The sale to ZGS was finalized on March 11 of that year.
2012–2014[]
During this logo's run, NBCUniversal entered into an agreement to acquire WWSI from ZGS Communications for $20 million on March 21, 2013. Prior to the sale agreement, WWSI had been the largest station (in terms of market size) aligned with Telemundo that was not an owned-and-operated station of the network. The sale was completed on July 2. The deal created a duopoly with NBC-owned Philadelphia station WCAU.
