🇺🇦 Diana Kydysiuk

Eva Diana Kidisyuk was born in Kyiv, Ukraine, on 31 March 2014, the second child of Olena and Volodymyr Kydysiuk. Her parents had begun making videos as a hobby around the birth of her older brother Roma in 2012. The Kids Diana Show channel launched on 12 May 2015, when Diana was thirteen months old; the family's stated purpose at the time was simply to share clips with friends and relatives.

It did not stay that way. By 2017 both parents had left their jobs to run the channel full time. The family moved first to Miami and later to Dubai, and the operation grew into a multi-channel business: unboxing, pretend play, songs and light educational content, dubbed into nine languages across roughly fourteen channels.

In May 2020 the family signed with pocket.watch, the children's media studio, and that October a consumer products line — Love, Diana: The Princess of Play — launched exclusively at Walmart, spanning dolls, playsets, dress-up, bath products and furniture priced from about ten dollars to a hundred. At launch the brand cited 143 million subscribers across fourteen channels in nine languages and more than five billion views in a single month, making hers the second most-viewed United States-based channel at the time. A Love, Diana animated-hybrid series followed on Amazon Prime Video, Roku, Hulu and Samsung TV Plus, along with a mobile game.

The record-keeping started early. In 2021, at six, Diana first claimed the Guinness World Record for most subscribers for an individual female on YouTube, with 74.5 million. Three years later the figure had grown to 122 million subscribers and 102.86 billion views, measured on 16 May 2024, and in late September 2024 she and Roma travelled with their parents to the Guinness World Records office in Dubai to receive the certificates in person from an adjudicator.

The current pair of records was measured on 24 March 2025: 132,000,000 subscribers and 112,617,798,897 views — figures that place her main channel among the five most-viewed on the entire platform. By August 2025, third-party tracking cited by Guinness put her at roughly 136 million subscribers and 118.3 billion views.

Her own description of it has stayed notably small in scale. 'Being part of the Guinness World Records family is incredibly exciting. I never expected this to happen,' she told Guinness. 'When I first started, I just wanted the channel to get a few views, but I never imagined it would become my life.' Elsewhere: 'We started our channel as a side project, but it turned into something huge, and now we're breaking records!'

The family has made more than two thousand videos, posting once or twice a week. Diana has been open about the cost of that schedule alongside school. 'Balancing YouTube and school can be tough sometimes,' she said, 'but I've gotten used to it. Now, with my two younger brothers taking over the channel, it's been working out fine for me.' Her brothers Oliver and Adam, born in 2020 and 2023, have gradually taken on more of the on-camera work.

Named a Young Achiever in the Guinness World Records 2026 book, she offered a reflection that reads less like a slogan than like something learned. 'The most important thing I've learned since starting YouTube is that we should never take things for granted. Everything we have is the result of effort, opportunities or someone's support, and we should appreciate and be grateful for it.'

Her mother's advice to families considering the same path was blunt about the odds and honest about the requirement. 'For anyone dreaming of starting a YouTube channel, our advice is simple: never be afraid. Don't worry about failing or things going wrong. If you truly love what you're doing and feel it's your calling, just start.'

Away from the camera the published details are ordinary: roller skating, doodling, do-it-yourself projects and home-made slime, and a reading habit. Her stated favourite book is Stephen King's Fairytale — which is, for a twelve-year-old whose working life has been spent in a pastel-coloured playroom, a small and welcome sign of a life of her own.

The scale of the numbers deserves a moment. One hundred and twelve billion views is more than fourteen views for every person alive. It is a figure achievable only in the children's category, where the same video is rewatched dozens of times by the same viewer, and where the audience turns over completely every few years as children age out and a new cohort arrives.

That dynamic is why family channels dominate YouTube's all-time view charts and why the biggest of them are effectively toy companies with a distribution arm attached. The Love, Diana line at Walmart, the animated series on four streaming platforms and the mobile game are not merchandise bolted onto a channel; they are the business model the channel exists to feed.

It is also a category under scrutiny. Regulators in several countries have tightened rules on advertising to children and on the earnings of child performers online, and platforms have restricted data collection and comments on content made for kids. A channel begun in 2015 as a hobby now operates inside a regulatory framework that did not exist when Diana was filmed for the first time at thirteen months old.
