[7] NewsFix maintains a faster-paced format than conventional television newscasts, incorporating an average of 33 segments per broadcast, about half of which focus on local stories.

[9] The idea for the program was conceived by Tribune Company chief innovation officer Lee Abrams (who resigned in October following complaints surrounding an inappropriate company-wide e-mail) in collaboration with KIAH news executive producer and Imaginator Gary Jaffe, as an alternative to newscasts Abrams deemed to follow "the 1970s television playbook".

[6] The Houston outlet would serve as the pilot station for the format to be named NewsFix, described by then-KIAH general manager Roger Bare in an interview with TVSpy as "a newsreel updated for the 21st century,"[7] which would only utilize an off-camera narrator to provide continuity for story and segment packages, requiring a far smaller staff to produce the broadcasts compared to traditional local news programs.

[11][12] Station employees were informed that the rebooted newscast would feature "fast-paced stories, added special effects and a minimum of on-camera appearance by reporters or anchors.

"[13] A pilot outlining the proposed format, produced at sister station WPIX in New York City, was presented to Tribune staffers in August 2010.

[10] Due to logistical issues that needed to be assessed (including workflow reconfiguration, staff training and production upgrades), the format launch was delayed three times – first to December, then to January 2011 and finally to March 2011.

[1] Monthly ratings for the late evening broadcast dropped from a 1.0 in April to 0.9 in the May sweeps period (from a high of 3.3 in December 2009 before the reformatting), before increasing to a 1.2 in August.

[22] Following the departures of four on-air staffers,[22][23][24] Larissa Hall (senior producer of KDAF's morning program EyeOpener) was promoted to "director of content" to oversee the station's newscasts in August 2012,[22] developing a format called Nightcap, incorporating multimedia journalists (which require a single person to film, edit and report news stories) and humor within most of its story content, in order to reduce costs and make the broadcast profitable.

Newscasts returned to WSFL in June 2021 with 7-9 a.m. and 10 p.m. editions of Local 10 News produced by BH Media-owned ABC affiliate WPLG.
