brief test pattern at 12:00 p.m. that day, followed by a loop of public service announcements from the National Association of Broadcasters (NAB) to inform viewers of the digital transition. The analog signal remained in lame-duck operation until June 26. On November 19, 2009, a fire in the electrical room of the station's Broadcast Hill studios knocked both stations off the air. Fire alarms were activated throughout the facility at 9:30 p.m. that evening, which resulted in staff members being evacuated from the studio; this resulted in the disruption of that evening's scheduled broadcasts of the 10:00 p.m. newscasts seen respectively on KXAS and KXTX. On February 12, 2013, LIN Media chose to withdraw its interest in the Station Venture Operations joint venture as part of a corporate reorganization. Through the dissolution of the arrangement, NBC gained full ownership of KXAS and regained exclusive ownership in KNSD. On May 4, 2011, KXAS-DT2 became an affiliate of NBC Nonstop (under the branding "NBC DFW Nonstop"), a programming format exclusive to the subchannels of NBC's O&Os that featured a mix of originally-produced news and lifestyle programming and rebroadcasts of KXAS's newscasts; NBC Nonstop was relaunched as the classic television network Cozi TV on December 20, 2012. In June 2012, NBCUniversal announced plans to construct a new facility in Fort Worth (located at the CentrePort Business Park on the former site of Amon Carter Field) to house KXAS, KXTX and NBCUniversal's other Dallas-based operations (including the Dallas news bureau operated by NBC News). Construction of the facility began that month, and was completed in September 2013, with the building formally opening on September 30. The facility incorporates four production studios; three control rooms that relay high definition content; an combined media asset management center and newsroom production suite for managing and editing content; and an expanded weather center within the production studio housing KXAS' main news set that contains upgraded software systems, an expert desk and two touchscreen monitors; the station's traffic and sales departments, which were previously in separate areas of the Broadcast Hill studios, were also placed adjacent to the newsroom. The sales and marketing departments of the television stations, and NBC's ArtWorks graphics firm began migrating their operations to the facility in early October of that year; all other operations—including the news departments of KXAS and KXTX—moved to the Carter Boulevard studio by November 1, ending KXAS's 65-year tenure at
