Audio series and audiobooks are stories that you listen to on your phone instead of reading them. An audiobook is a book read aloud by a narrator. An audio series is a story written for listening, told in hundreds or even thousands of short episodes. Indian apps built the audio series into a large business, with tens of millions of listeners, many of them in Hindi, Tamil, Bengali and other Indian languages.
Here is a typical case. You are on the Delhi Metro, on your way to work. You open an audio series app and start a Hindi thriller. Each episode lasts about ten minutes, so you finish two or three episodes on each journey.
The story did not start in the app. It started on an online story writing platform, where a writer published it chapter by chapter, for free. Many readers liked it, so the audio app bought the right to turn it into audio. Writers turned the chapters into scripts, and voice artists recorded them. This work is described in audio drama production. Some apps now also use speech and voice AI to voice episodes, or to make a version in another language.
The first 20 episodes are free. Episode 20 ends on a cliffhanger: the hero opens a door, and someone is standing behind it. To hear episode 21, the app asks for coins. Coins are the app's own money. You buy them with real money, through UPI, and spend them inside the app. Here, ₹49 buys enough coins for about 8 episodes. Money of this kind is called virtual currency. A loyal listener of a 700-episode series can spend more on it than on a printed book.
A month later, you finish the thriller. Now you want to hear a well-known Hindi novel, read by a professional narrator. For that, you use an audiobook subscription. You pay one monthly fee, and you can listen to any book, story or course in the app's library.
So stories on the phone are paid for in three ways. Audio series earn by the episode. Audiobooks earn by subscription. Written stories are mostly free, and they earn when readers pay to unlock some chapters. Many people will not pay at all, so some apps also play ads. These ways of paying are compared in AVOD, SVOD and TVOD.
Why do Indian languages matter so much here? Hundreds of millions of Indians came online on cheap phones, and many of them prefer to read and listen in their own language. English-first services did not reach them. This is described in the vernacular internet. The pay-by-episode idea also works for video. A micro-drama app sells dramas filmed upright for the phone, in episodes one or two minutes long, one episode at a time.
