it has had to fend off a strong challenge from a resurgent WVUE. In 1984, WDSU built the first working television studio at a World's Fair for the station's live broadcasts from the event held in New Orleans that year. On February 17, 1986, WDSU became the first NBC affiliate in Louisiana to broadcast its programs in stereo. Cosmos sold WDSU to Pulitzer, Inc. for $47 million in 1989. Under Pulitzer, channel 6 finally dropped the "-TV" suffix from its calls in 1993, more than 20 years after it and its former radio sisters had gone their separate ways. In March 1996, the station moved into its current facility on Howard Avenue, located a few blocks from the Le Pavillon Hotel, where WDSU radio began operations in 1923. Also during the 1990s, WDSU became the first New Orleans station to operate its own Doppler weather radar system ("Super Doppler 6000"). Pulitzer sold its entire television station division, including WDSU, to Hearst-Argyle Television (predecessor to the present-day Hearst Television) in 1999 for $1.8 billion. WDSU celebrated its 60th anniversary of broadcasting on December 18, 2008. Since 2009, WDSU has simply branded with its callsign in most verbal references, despite retaining the "channel 6" red dot logo it has used since 2000. In 2015, the NBC Peacock logo was added to the "channel 6" red dot logo, due to the network's requirement that the NBC logo be included with any affiliate's logo. Hurricane Katrina Prior to the landfall of Hurricane Katrina, WDSU shut down operations at its studios in New Orleans around 9:30 p.m. on August 28, 2005, in order to allow station staff to take shelter from the oncoming hurricane. At that point, WDSU's broadcasts began to originate from the studios of ABC-affiliated sister station WAPT in Jackson, Mississippi, where some of WDSU's on-air staff had already evacuated. Fellow sister station, NBC affiliate WESH in Orlando, Florida, also originated some on-air weather content during the storm. In the weeks that immediately followed the hurricane, WDSU's news programming originated from the WAPT facility, using meteorologists and anchors from both stations, with programs being simulcast in Jackson and New Orleans. The Howard Avenue studio facility largely withstood Hurricane Katrina with minimal damage, but WDSU's analog and digital transmitters were both destroyed in the storm. In early September, WDSU arranged to transmit its signal via i: Independent Television affiliate (now Ion Television owned-and-operated station)
