Laff's launch was announced by
Katz Broadcasting in January 2015 as having a scheduled launch date of , coinciding with
Tax Day in the United States; the explanation by Katz is that people needed "something to laugh to" on what they deemed one of the most stressful days of the year. The network launched at noon that day; the first program was the film ''
My Mom's New Boyfriend''. Katz announced that television stations owned by
ABC Owned Television Stations and 13
E. W. Scripps Company would serve as the network's charter affiliates; the former serving as a replacement for the standard definition feed of the
Live Well Network, which with Laff's announcement also began to roll-back to only being carried by ABCOTS stations. On March 13, 2015, Katz Broadcasting announced an affiliation deal with the
Cox Media Group to carry Laff on the subchannels of seven of its stations expanding its initial reach to 47% of the country. The following week on March 20, as part of a multi-network affiliation agreement with Katz, the
Meredith Corporation announced that it would carry the network on two of its stations. Additional affiliation deals were struck later in the year with
Media General,
Tribune Media, and
Griffin Media. On February 13, 2015, Laff acquired the
syndication rights to five sitcoms. Laff soon signed film rights deals with
Disney–ABC Domestic Television,
Miramax, and
Sony Pictures Television by March 17. Laff made a multi-year deal for five sitcoms with
Carsey-Werner Productions in April 2016.
Roseanne reruns were removed on May 29, 2018, after
Roseanne Barr was fired from the show by ABC (which then continued on as
The Conners); both decisions were based on
a Roseanne Barr tweet considered racist. A list of 2019
Nielsen ratings published by
Variety indicated that Laff averaged 223,000 viewers in prime time, down 5% from the 2018 average. The network moved off
ABC Owned Television Stations at the beginning of 2021, in favor of new carriage on Scripps' newly-acquired
Ion Media stations in place of the now-defunct
Qubo,
Ion Plus and Ion Shop networks. In July 2023, the managing company of Laff announced an
over-the-top streaming channel counterpart of Laff, called Laff More. To honor the 10th anniversary of the network's launch, the network unveiled a temporary new
digital on-screen graphic logo beginning in April 2025, with the Laff typeface enclosed inside a number 10. They would also air a specially-marked "Special Presentation" of the 2025
Scripps National Spelling Bee, an event run by network owner E.W. Scripps Company, on May 28 and 29, 2025. ==Programming==
