Pop was originally launched on 29 May 2003 by Chart Show Channels (CSC) Media Group as Toons&Tunes. Toons&Tunes was then later rebranded as its current name, Pop (formerly stylized as pop and POP!) in the following month.

In the channel's early years, links were presented by Rorry, a lime green dragon with a Scottish accent, who was animated live. He was accompanied by Purrdy, a dragon/cat hybrid who also appeared in the original Tricky programme on ITV1, it was sometimes followed by a programme known as "The Cheeky Monkey Show" which features the live links of the animated coloured monkeys known as "The Cheeky Monkeys," that was later known by appearing on its sister channel Tiny Pop until its retirement at the end of June 2009.

Originally, the network focused on music videos with animated programming also part of the schedule, but with the numerous music video network options on British television at the time, this focus was quickly abandoned in 2004, when the animated content became much more prominent. Music videos continued to be carried on and off until 2010, before eventually being abandoned entirely.[citation needed, In 2010, Pop had several popular shows, such as The Smurfs, GoGoRiki, Oggy and the Cockroaches, etc.

In 2012, Pop introduces semi-mascots known as the MoonGoons, These are animal-like aliens, with the 2 main ones being a blue squid named Boofus and an orange rabbit named Diggle, These were gone by the time of the channel's next rebrand in 2015, Also in 2014 CSC Media Group had folded into Sony.

On 1 September 2020, Pop rebranded its on-air identity, with the premiere of Bakugan: Armored Alliance. And on the same day, starting with Pokémon Journeys: The Series, the network became the new British home of the Pokémon anime, moving from its previous broadcasters, ITV1 and CITV, of over 20 years. The channel was also sold by Sony to Narrative Entertainment

On 9 November 2022, Narrative Entertainment announced the launch of a new FAST channel, Pop Kids, to stream on Samsung TV Plus, the new FAST network airs shows from Pop and Tiny Pop.

Sometime in 2022, Pop began to branch into YouTube content, as they approached Joe Tasker for a new show called Swipe It! With Joe Taker, they would later acquire from content creators to use on their channel, including LankyBox, Denis and EthanGamer (the latter exclusively airing on Pop Player).

By 2023 Alvin & the Chipmunks, Squish, Miraculous Ladybug and Pokemon were among the channels popular shows, 

Now here is when things start to diverge from the real world, In June 2023 (in my alternate universe) the channel was sold to UKTV, In September the channel introduced Toonattik, a revival of the CITV programming block of the same name, Write a blog post where at the end of a Toonattik show on November, Jamie and Anna are saying to come back tomorrow for Squish, when they hear chittering noises, Jamie says "Pop got rid of them years ago?"

With the promised reveal just moments away, the air was thick with anticipation on this morning’s episode of Toonattik. Jamie and Anna could barely contain their excitement as they climbed up the attic stairs, the site of yesterday’s mysterious happenings. As the attic door creaked open, they were met with a scene both heartwarming and nostalgic.

There, frolicking among a few old props and cobwebs, were the beloved semi-mascots of Pop’s past – the MoonGoons! Boofus, the friendly blue squid, and Diggle, the cheerful orange rabbit, greeted Jamie and Anna with open arms and their trademark playful antics. The studio erupted into surprised cheers and laughter as children and parents at home rejoiced at the reunion with old friends.

“Looks like these guys were the source of the puzzling sounds and that rogue tentacle!” Jamie exclaimed, ruffling Boofus’ squidgy head.

Anna added with a smile, “And it seems they’ve brought along a feather from their adventures to share with us. Welcome back, you two!”

The MoonGoons’ return was a delightful throwback for seasoned Pop fans, and a fresh introduction to newer viewers who might be meeting the charming characters for the first time.

But the surprises didn’t stop there. After the MoonGoons settled in, Jamie announced, “Now that our attic explorers have been revealed, it’s time for another special announcement. Right after today’s episode of Squish, we’ve got another old favourite making a comeback.”

Drumrolls echoed through the studio as Anna chimed in, “It’s none other than GoGoRiki! We were thinking of throwing in Alvin & the Chipmunks, which you all love, but instead, we decided to shake things up with a classic that deserves some limelight.”

“GoGoRiki offers the perfect dose of whimsy and fun following the squishy shenanigans of Squish,” Jamie continued, reflecting the gleeful atmosphere.

Social media lit up once more as fans young and old expressed their glee at the unexpected schedule. Before long, #Toonattik, #MoonGoons, and #GoGoRiki were trending, as conversations about favorite episodes and characters dominated online discussion.

As the show wrapped up for the day, Jamie and Anna, joined by Boofus and Diggle, waved goodbye to the viewers. “Don’t forget to tune in tomorrow for more exciting adventures here on Toonattik. Who knows what or who might turn up next in our attic!”

Pop’s Toonattik, with its reimagined content and loving nods to its rich history, has proven that the channel remains a staple for children’s entertainment. It’s the perfect blend of the old and the new, wrapped up in a programming block that continues to capture imaginations, one animated adventure at a time.

After this, the MoonGoons once again became the channel's adored mascots, GoGoRiki was soon after permanently placed back on the schedule. Write a blog post for the cliffhanger on Saturday's show
