Rai Gulp began broadcasting on 1 June 2007 as a replacement of Rai Doc and Rai Futura, the latter two were closed shortly before its launch.
Since 2009, when RaiSat Smash Girls end broadcasting in 2009, some programs that were broadcast on that channel have been present in the schedule of the channel.
From 27 April 2010, the programming of the channel has been coordinated by the Rai Ragazzi structure.
Since autumn 2010 the channel slightly changed graphics, (for example in promos and bumpers) and changed its target audience into the range from 8 to 14 years. New cartoons, children's fiction, and other products are added.
On July 31, 2014 the channel began broadcasting new episodes of the Italian-American animated series Winx Club, previously shown on Rai 2. However, starting from April 15, 2019, Rai Gulp only airs re-runs of the show, with new episodes now being shown on its sister channel Rai Yoyo.
Since 1 January 2011, the official speaker of Rai Gulp is the voice actor Emanuele Ruzza.
Since 13 December 2016, the channel has been broadcasting the oldest cartoons with 4:3 format in the 16:9 pillar-box panoramic format, as well as Rai Yoyo, as well as all the other Rai digital terrestrial channels.
From 4 January 2017, the channel is visible in high definition on Tivùsat.
On 10 April 2017, the channel renews its logo and graphics at the same time as the other Rai channels.
On April 14, 2017, Luca Milano replaces Massimo Liofredi as head of Rai Gulp and Rai Yoyo.
From July 2020 onward, Rai Gulp no longer has its own website but is visible in streaming on RaiPlay.
From December 2021, the SD version closed on Tivùsat, so the HD version is now FTA
