If you were to jump through a portal of time to 15,000 BCE, you would find art on cave walls. By 500 BCE, in parts of the world like Greece, artists would have enclosed images within decorative frames; by 1500 CE, the Renaissance would have solidified the rectangular frame as the dominant format. The 1890s are sure to have brought cinema’s near-square 1.33:1 frame, followed by wider aspect ratios in the 1950s that launched the widescreen revolution, making way for the cinema we know today.Now return to 2026. Open a mobile application like KadhaiShorts or Jio Hotstar’s Tadka, and you will encounter something equally revolutionary — series storytelling in a vertical format covering much of your smartphone screen in a 9:16 aspect ratio. That is not all. Episodes now span less than three minutes, another revolution. Welcome to the era of vertical cinema and micro-dramas.With Instagram and YouTube getting audiences used to bite-sized vertical content, filmmakers have started to make films and shows for these platforms. While micro-dramas have been getting popular globally in the last few years, they exist mostly as sketch videos in India. This is changing. According to a report by Ormax Media, almost 65 per cent of Indias’s audience discovered micro-dramas within the last year; and 89 per cent of them discovered the format through social media platforms. Now, a rush of micro-drama platforms — Kuku TV, Quick TV, Chai Shots, Story TV, Tuktuki, and MX Fatafat among others — are creating gripping narratives that aim to capture your imagination without taking up much space or time.JioHotstar has been pushing this format in a new mobile-only segment called Tadka in their application. “Audiences still love immersive long-form storytelling, but they are also looking for stories that can fit naturally into the spaces between those larger viewing occasions. We saw an opportunity to build a new storytelling layer designed specifically for that behaviour,” says Ambuj Kashyap, executive vice-president, Micro Content at JioStar.
