Programming Service, LLC uplinked the station again exclusively for satellite subscribers. The national feed was once again the same feed as the New York market feed. NPS dropped WWOR in 1999, in favor of Pax TV, but Dish Network still carries the New York feed of WWOR as part of its superstations package except in areas where the local UPN (and later, MyNetworkTV) affiliate invoked SyndEx to block the feed. In 2000, Chris-Craft announced that it was selling its television stations. It was believed that Viacom, which had purchased Chris-Craft's half of the network that year not long after buying CBS—gaining full control of UPN (and effectively stripping WWOR of its status as an owned-and-operated station of the network in the process), would buy the stations. However, Viacom lost its bid for the group to the Fox Television Stations subsidiary of News Corporation on August 12, 2000, in a $5.5 billion deal, making WWOR-TV a sister station to longtime rival WNYW—creating a unique situation in which the largest affiliate station of one network was owned by the operator of another network. While some cast doubt on UPN's future, Fox quickly cut a new affiliation deal with UPN. On September 11, 2001, the transmitter facilities of WWOR-TV and eight other New York City television stations and several radio stations were destroyed when two hijacked airplanes crashed into and destroyed the World Trade Center towers. With its broadcast signal shut down, WWOR fed its signal directly to cable and satellite systems, running wall-to-wall coverage of the attacks from CNN and later the Fox News Channel. The station's website received unprecedented traffic but remained available, including streaming video of pre-recorded newscasts. Channel 9 resumed regular programming on September 17, 2001. The station installed a new transmitter at the Empire State Building (where the transmitter had been based prior to 1975) along with most of the other major New York City stations, until moving back to One World Trade Center in 2018. The attacks delayed the closing of the Chris-Craft deal for several days. Fox began integrating the operations of its two stations soon afterwards. In the fall of 2001, the Fox Kids weekday afternoon block moved to WWOR-TV from WNYW, while the station also ran UPN's Disney's One Too during the morning hours. Channel 9 was New York City's last remaining commercial station to air children's programming on both weekday mornings and afternoons,
