Even though Boomerang is supposed to air archival content, it has aired New Episodes of various shows since 2015 in various programming blocks under the "New Episodes" banner.

New Episode Weekends Edit

New Episode Weekends was the first of these blocks, which ran from January 10, 2015 to July 12, 2015. It aired Grojband, Numb Chucks, and The Garfield Show on weekend afternoons from 1 to 3 pm.

New at 8:30 Edit

New at 8:30 aired from October 5, 2015 to January 29, 2016, and would air new episodes of a different show on weekday nights at 8:30 pm. It aired Be Cool, Scooby-Doo!, Wabbit, The Garfield Show, Shaun the Sheep, Dreamworks Dragons, Sonic Boom, and Transformers: Robots in Disguise.

The Garfield Show Weekdays Edit

After New at 8:30 ended, new episodes of The Garfield Show continued to air until October 28, 2016, with re-runs continuing to air until December 30, 2016.

Saturday Morning Premieres Edit

Saturday Morning Premieres aired on Boomerang from February 6, 2016 to June 25, 2016, and featured new episodes of Wabbit, The Tom and Jerry Show, Be Cool, Scooby-Doo!, and Bunnicula, airing them from 9 to 11 am. For cross-promotional purposes, it also was simulcast on Boomerang's sister channel, Cartoon Network, until March 12, 2016. When the block ended, Bunnicula was removed from Boomerang's line-up entirely, while The Tom and Jerry Show, Wabbit, and Be Cool, Scooby-Doo! continued to air on Boomerang until August 1, 2016, October 31, 2016, and March 5, 2017, respectively. Boomerang later added new episodes of the shows featured on the block to its SOVD service beginning on the service's launch on April 11, 2017, and has burned off those episodes since then, airing them in graveyard timeslots, unadvertised, since May 2017.

Shaun the Sheep Weekdays Edit

On January 2, 2017, Shaun the Sheep began airing new episodes on weekdays, replacing The Garfield Show. The series left Boomerang on July 3, 2017.

Weeknights at 8 PM Edit

Weeknights at 8 PM launched on April 3, 2017, replacing Teen Titans Go!, and ended on November 3, 2017, when it was replaced by Ben 10 (2016 TV series). The block aired new episodes of Grizzy and the Lemmings and My Knight and Me on weekday nights at 8 and 8:30 pm respectively. When the block ended, Grizzy and the Lemmings moved to weekday evenings at 5 pm, before moving to the Weekends at 1 PM block (see below) on January 8, 2018, and My Knight and Me began airing weekday afternoons at 1 pm, before moving to every morning at 6 am on January 1, 2018, then, finally, its current timeslot of only weekend mornings at 6 am on May 27, 2018.

Weekends at 1 PM Edit

New episodes of Peanuts had been shown on weekends since July 1, 2016, replacing Bunnicula. On January 6, 2018, Grizzy and the Lemmings also began airing new episodes on weekends, turning the timeslots used into a new block, Weekends at 1 PM, the brand's most recent block. The block ended on March 4, 2018, with Grizzy and the Lemmings leaving Boomerang's line-up entirely, and Peanuts moving to weekday evenings at 5 pm, before it also left Boomerang's schedule, on April 1, 2018.

However, on April 30, 2018, Peanuts and Grizzy and the Lemmings both returned to Boomerang's schedule, with the two shows switching their timeslots with each other everyday, with one of the two shows airing for a half-hour at 11:30 am, and the other show airing for an hour at 1 pm. Grizzy and the Lemmings left Boomerang's schedule again on May 20, 2018, with Peanuts now airing only for an hour on weekends at 7 am as a result of this.
