2015–2021: Revival

At the 2014 Cartoon Network upfront, another series titled Wabbit: A Looney Tunes Production (later New Looney Tunes) was announced. Starring Bugs Bunny, the series premiered on both Cartoon Network and its sister channel Boomerang in late 2015. The series had an unusually slow rollout, with the series being moved to the Boomerang streaming service in 2017, and was eventually cancelled on January 30, 2020.

On June 11, 2018, another series, titled Looney Tunes Cartoons, was announced by Warner Bros. Animation. It premiered on May 27, 2020, on the streaming service HBO Max. The series features "1,000 minutes of new one-to-six minute cartoons featuring the brand's marquee characters", voiced by their current voice actors in "simple, gag-driven and visually vibrant stories" that are rendered by multiple artists employing "a visual style that will resonate with fans", most noticeably having a style reminiscent of the styles of Tex Avery, Bob Clampett, Chuck Jones, Friz Freleng and Robert McKimson. According to co-executive producer Peter Browngardt, "We're not doing guns, but we can do cartoony violence — TNT, the Acme stuff. All that was kind of grandfathered in." Sam Register, president of Warner Bros. Animation also served as a co-executive producer for the series. The series ended on July 27, 2023.

On February 11, 2021, it was announced two new series were in the works: Bugs Bunny Builders and Tweety Mysteries. Bugs Bunny Builders began airing on Cartoon Network as part of Cartoonito and HBO Max on July 25, 2022; Tweety Mysteries would also air on Cartoon Network. Bugs Bunny Builders is aimed towards preschoolers; while Tweety Mysteries is a live-action/animated hybrid. However, the latter was scrapped for unknown reasons.

A sequel to Space Jam titled Space Jam: A New Legacy, starring basketball player LeBron James, was released in theaters and HBO Max on July 16, 2021, after a Los Angeles special screening on July 12, 2021. It is a film with a story of LeBron James' second son, Dom, who gets kidnapped by an evil AI named Al. G Rhythm (Don Cheadle), into the Warner Bros. server-verse. LeBron then assembles the Tune Squad to play against the algorithm and get his son back. It received generally negative reviews and underperformed at the box office.
