The Sun Sentinel website has news video from two South Florida television stations: West Palm Beach's CBS affiliate WPEC and Miami and Fort Lauderdale CW affiliate WSFL-TV; it was a former sister station to the latter before Tribune's publishing and broadcasting interests were split.

The Sun Sentinel traces its history to the 1910 founding of the Fort Lauderdale Weekly Herald, the first known newspaper in the Fort Lauderdale area, and the Everglades Breeze, a locally printed paper founded in 1911, which promoted itself as "Florida's great Farm, Truck and Fruit Growing paper.

In 1953, Gore Publishing changed the name of the paper to the Fort Lauderdale News and added a Sunday morning edition.

In 2004, the paper won the Payne Award for Ethics in Journalism for its coverage of health and human services in the state.

[17] On August 17, 2008, the Sun Sentinel unveiled a redesigned layout, with larger graphics, more color, and a new large "S" logo.

This is in tune with another Tribune newspaper (Orlando Sentinel), which redesigned its newspaper a few months previously, and created a brand synergy with Tribune's sister operation and CW affiliate WSFL-TV (Channel 39), which relocated its operations to the Sun Sentinel offices in 2008 and adopted a logo matching the capital "S" in the new logo.

These advances include: launching the pure-play entertainment website SouthFlorida.com and starting a video channel called SunSentinel Originals.

In April 2013, the Sun Sentinel won its first gold medal in the category of Public Service Journalism, for its investigative series about off-duty police officers who engage in regular reckless speeding.

[24] In September 2008, a Bloomberg L.P. employee saw a six-year-old Chicago Tribune article posted on the Sun Sentinel's website about United Airlines' 2002 filing for bankruptcy and, due to its unclear display, mistakenly thought it was a recent story.

[26] As a result, there was a massive selloff of United Airlines stock, and its share price temporarily dropped "from $12 to $3 before trading was suspended.

[30] Since 2018, the Sun Sentinel has been preventing internet users in the European Union from accessing its website, on grounds of missing data protection compliance.
