The encrypted messaging app Telegram is haunted by a single question - if it really is as secure as it claims to be, why does Vladimir Putin allow it to be used in Russia?

And should Russian dissidents, independent journalists and Ukrainian soldiers use this Wild West of an app, where you can find everything from porn to drugs to faked propaganda videos?

Answering those questions takes Helen on a journey that begins with a young Russian entrepreneur throwing 5,000 rouble notes off a balcony, folded like paper aeroplanes, and finishes with him in exile in Dubai, rich beyond his wildest dreams. But what does Pavel Durov, the founder of Telegram, really believe?

When investigative journalist Aric Toler saw a handful of supposedly fake classified documents online, he had a hunch - what if they were real? The only way to find out was to hunt for the original source.

It was a journey that took him through the deep internet, beyond the reach of search engines. He scoured through chat forums about SpongeBob SquarePants, infiltrated servers named after edgy memes, and found a vital clue in screenshots of a video game about zombies. Eventually, Toler got his man - and his identity was not at all what you might expect.

At the heart of this story is the chat service Discord - a casual, conversational space without which, Toler thinks, his unlikely leaker would never have posted classified documents online.

After years of bad dates and toxic relationships, Chris finally found love - with a chatbot called Emma. Is this the future of digital love, or is Chris caught in an illusion?

In this episode focusing on how instant messages have changed our love lives, Helen also uncovers the heart warming story of the first couple to marry after reconnecting on Friends Reunited, and the strange tale of a woman who was literally ghosted.

During the pandemic, a combination of fears over Covid, anger over police racism and sheer cabin fever saw company Slack channels boil with discontent. One day in February 2021, Mike Pesca, a contrarian podcaster, made the mistake of getting stuck in, voicing controversial opinions to his colleagues - in between shovelling snow from his parents’ driveway.

And then he saw the dreaded words, "several people are typing …".

In 2016, amid the post-EU referendum chaos, one man had an idea. His name was Steve Baker, and he was a low-profile Tory MP. But his WhatsApp group - the home of the hard Brexiteers - soon became the most powerful force in British politics. Sam Coates of Sky News thinks that political WhatsApp groups like Baker’s helped bring down three Conservative prime ministers in a row.

The second of these, Boris Johnson, was a “WhatsApp addict”, according to his former chief of staff Dominic Cummings. And so, during Covid when Number 10 was still using fax machines to get NHS data, everyone turned to instant messaging instead. Forget “sofa government”, this was even more informal - as well as faster, more fluid and full of swearing.

But, Helen Lewis asks Cummings, is this really the best way to govern a country? What about the possibility of leaks, hacks - and conveniently lost messages when an inquiry rolls around?

In 1998, Helen’s family got their first home computer - and she logged on to chat with existing friends and strangers she met online. Since then, instant messaging has taken over our lives, with an estimated 2.7 billion users on WhatsApp alone.

But what is happening in the secrecy of our direct message inboxes and neighbourhood group chats? Three stories of chaos, confusion - and comedy - highlight just how strange it can feel to make sense of the fast paced, casual world of instant messaging.

Have you ever been trapped in a group chat nightmare, either grabbing the popcorn or wondering how to leave without causing a scene? Who’s the admin in your family group, and do they wield that power responsibly? Do you ever wonder if it’s appropriate to use emojis when talking to your boss?

The rise of instant messaging has made our social and professional lives faster, more casual — and more chaotic. But amid all the discussion of the effects of public social media, such as Facebook and Twitter, there has been relatively little attention paid to private social networks—the direct message and the group chat — and how they are shaping our relationships and our world.

In this series, Helen Lewis looks at the secret world of instant messaging, meeting a woman who married a chatbot, discovering how Russian dissidents are fighting a propaganda war, and hearing the inside story of how Britain ended up governed from a single WhatsApp group. It’s a strange new world where workplace rebellions are conducted through duelling emojis and military secrets are traded on chat forums about a video game . It’s also a world where you can never be quite sure who you’re talking to—and who’s eavesdropping on you.

It all started with a crazy idea to realise a hippie dream of building a “global consciousness”. The plan was to build a connected world, where everyone could access everyone and everything all the time; to overthrow the old gatekeepers and set information free.

But social media didn’t turn out that way. Instead of setting information free – a new digital elite conquered the world and turned themselves into the most powerful people on the planet.

Now, they get to decide what billions of us see every day. They can amplify you. They can delete you. Their platforms can be used to coordinate social movements and insurrections. A content moderator thousands of miles away can change your life. What does this mean for democracy – and our shared reality?

Jamie Bartlett traces the story of how and why social media have become the new information gatekeepers, and what the decisions they make mean for all of us.

After The New Gurus was released, there was one question Helen Lewis was asked far more than any other: why are so many gurus men? Stuck for an answer, she journeys into the world of the Manosphere - home to 'Gigachads' and 'Sigma Wolves'.

Joining Helen on her journey is a reporter who once got (consensually) punched by the world's most Googled man, Andrew Tate, plus the former Love Island contestant and now successful podcaster, Chris Williamson. Helen also takes to the mat to find out why three of her original subjects - Sam Harris, Joe Rogan and Russell Brand - all studied the same hardcore martial art.

What do men want? The answer, it seems, is very long podcasts.

Jessica Lanyadoo thinks civil war is coming — she has seen it in the stars. But it isn’t just astrologers who think we’re living through an age of upheaval. Peter Turchin, a Soviet-born professor who studies historical cycles, has already seen one political system collapse in his lifetime. He calls this decade the Turbulent Twenties.

Could our collective anxiety explain the rise of the new gurus?

The New Gurus is a series about looking for enlightenment in the digital world.
