Why Vertical Dramas Are So Popular

Vertical dramas, like "Don't Challenge the Lady Billionaire", often feature recurring themes such as secret billionaires, rags-to-riches storylines, and enemies-to-lovers romances. While the stories and titles can feel familiar, the genre has grown rapidly worldwide.

Vertical dramas are being called "TV for the TikTok generation." These shows have minute-long episodes, often totaling 60 to 120 episodes. They're designed for smartphones and can be consumed in a single sitting.

The format banks on instant gratification, which has helped make the genre extremely popular. The industry is projected to be worth $14 billion by 2027.

In November 2024, the California-based, Chinese-backed ReelShort overtook TikTok as the most popular product in the entertainment section of Apple’s app store in the US and has been downloaded more than 30 million times since its launch in 2022.
