Owned by Nexstar Media Group as sister to NBC affiliate WFLA-TV (channel 8) and CW owned-and-operated station WTTA (channel 38), the station's Suncoast News Network (SNN) service provides news coverage focusing primarily on the North Port–Bradenton–Sarasota Metropolitan Statistical Area (including Sarasota, Manatee, and Charlotte counties).

SNN received national attention in 2007, when a clip of chief meteorologist Justin Mosely (who worked with the channel from 2004 to 2013 and returned in March 2014) reacting frightened after a cockroach crawled up his leg during a live weather segment went viral after it was posted on various video websites including YouTube.

In November 2008, the Sarasota Herald-Tribune (then owned by The New York Times Company) announced that it would sell SNN News 6, and stop broadcasting at the end of December 2008.

On February 26, 2009, after a four-week hiatus, SNN was back on the air under the management of LDB Media, LLC, with the majority of its former on-air staff.

On September 24, 2014, Citadel announced that SNN's operations would be merged with its over-the-air television station in Sarasota, WLWN-LD (channel 39), on October 15; as part of the consolidation, WLWN changed its call letters to WSNN-LD.

Since 2002, SNN has maintained a content-sharing agreement with Tampa-based NBC affiliate WFLA-TV (channel 8) and NBC News, which allows SNN to use stories from WFLA, NBC News and NBC-affiliated stations (that agreement replaced an earlier deal between the channel, Fox owned-and-operated station WTVT (channel 13), and the now-defunct CONUS Communications), and also allowed for cooperation between the Herald-Tribune and the Tampa Tribune, prior to Media General's sale of that paper to World Media Holdings in 2012.

It is unclear if SNN will be moving to the new facility as in 2018, Sarasota Memorial Hospital announced it would buy out the old Herald Tribune building and re-construct the entire area.

On May 19, 2023, Citadel Communications COO Ray Cole announced that WSNN-LD would be sold to Nexstar Media Group (owner of WFLA-TV and WTTA (channel 38)) for $1 million.
