Telegram: What’s behind the social media app’s growing popularity?

Telegram says it has 500 million users worldwide. Most use the app to chat, but there’s more to it than that.

BBC World Service Disinformation reporter Jack Goodman takes a look at what’s behind the rise of Telegram.

The BBC documentary, ‘Telegram: Why won’t you take my naked photos down?’ will be published later this week.
