either the primary channel or HBO Family since. (HBO Family continued to maintain a limited slate of original children's programming until 2003.) HBO ventured back into children's programming with its acquisition of first-run broadcast and streaming rights to Sesame Street, a long-running children's television series that had previously aired on the program's longtime broadcaster, PBS, for the vast majority of its run, in a five-year programming and development deal with Sesame Workshop that was announced in August 2015. Although struck with the intent to having the show remain on PBS in some fashion, the nonprofit production company reached the deal due to cutbacks resulting from declines in public and private donations, distribution fees paid by PBS member stations and licensing for merchandise sales. Through the agreement, HBO obtained first-run television rights to Sesame Street, beginning with the January 2016 debut of its 46th season (with episodes being distributed to PBS, following a nine-month exclusivity window at no charge to its member stations); Sesame Workshop also produced original children's programming content for the channel, which also gained exclusive streaming rights to the company's programming library for HBO Go and HBO Now (assuming those rights from Amazon Video, Netflix and Sesame Workshop's in-house subscription streaming service, Sesame Go, the latter of which will cease to operate as a standalone offering). With the debut of HBO Max in May 2020, under contract renewal terms agreed upon between the studio and WarnerMedia in October 2019, Sesame Street and other Sesame Workshop content will shift from the linear television service to the streaming-based HBO Max later in the year.

Since June 6, 1992, HBO has offered weekly pay television premieres of recent theatrical and original made-for-cable movies on Saturdays at 8:00 p.m. ET/PT. (Event presentations that have followed the movie—such as boxing coverage or concerts—have caused rare variances in the preceding film's start time; if a live event was scheduled, prior to the December 2018 discontinuation of HBO's boxing telecasts, the premiered film would air after the event—in reverse order from the Eastern feed scheduling—on
