There’s a lot of money to be made in the business of sleep. Take sunrise alarm clocks, fancy mattresses, REM-tracking wearables, and monthly deliveries of melatonin.

But should we really be investing this much in hopes of catching a few more Z’s?

In the final episode of season 8, we consult a bonafide sleep doctor on the matter and get a physician’s POV on a few questions keeping us up at night:

Why is there such a large market for catching some Z’s?

Can any of these products actually help us find rest? 

Why do we need to sleep?

What’s happening in our brains and bodies while we dream?

There are contactless thermometers, the Nose Frieda, co-sleeping. Trends in parenting gear and childrearing practices seem to evolve at faster rates than other sectors, a speed exemplified by a single product: strollers. 

While we’ve been engineering ways to wheel children around for centuries, stroller manufacturers can’t seem to stop iterating on their models. Strollers have become a status identifier, a repository for parenting anxiety, and an emblem of consumerism run amok. As doctors and experts gather new research and best practices in childcare, strollers exemplify how quickly it’s all changing.

Strap into episode 5 and get the latest about this new movement in industrial design.

From Dubai to Dublin to Dallas and back, air carriers are cashing in on a big business: credit cards. 

In fact, analysts note that growth in the sector “significantly outpaces the overall credit card industry.” One carrier alone can profit billions from its cards in a calendar year and, in tandem, build loyalty by tying them up in frequent flier programs. 

Why did airlines build out a business line through these little scraps of plastic? 

What’s the history of these co-branded cards? 

How did credit rewards come to make sky-high profits? 

Fasten your seatbelts and put away your tray tables as the fourth episode of season 8 takes off, with a co-pilot who’s made a business of this business: The Points Guy himself.

As the highest class of international racing for open-wheel, single-seater cars, F1 is worth more than $18B and stands to accelerate even more as a bonafide entertainment business as the Euro-born sport becomes more popular in China, the United States, and other global heavyweights. But F1 also faces its challenges, from new driving tech to adopt to new electrification pressures to confront. 

In this episode our Jalopnik colleague Ryan King guest-stars to navigate a few high-speed laps around the past, present, and future of Formula One racing.

Powering an electric car or truck is designed for people with private garages or who live in a major city with lots of accessible charging stations. Rural and suburban apartment-dwellers can’t just run cords out their three-story windows to juice up their rides through a 140-volt outlet. That would take days. 

If we want any shot at transitioning to greener vehicles, how can we turbo-charge access to EVs for everyone?

Get all the answers in our second episode of season 8.

Ever heard of Viagra, Rogaine, or Ozempic? 

The process for turning a chemical compound into a household name is both a science and an art. In fact, naming a prescription drug can take a manufacturer up to four years, as a set of three monikers per medicine must run the gauntlet of several regulatory agencies.

It all starts with determining a drug’s chemical and generic names — both of which involve established rules. After those are settled, the rest is marketing. 

So how do some drugs become memorable? What global trends dominate drug naming? And what happens when a company gets it wrong?

Get all the answers in our season 8 opener.

Bought something you don’t need from an ad? Blame it on the algorithm. Disappointing singles on your dating app? Blame it on the algorithm. Come across a post that hits too close to home? Yep, it’s the algorithm. But what exactly is the algorithm, and when did it start shaping how we live digitally? We track the making of the algorithm — starting with ancient Babylonians and Greek mathematicians — to understand the forces filtering what we stream, shop, and see online today.

Love a game, buy a game. Really love a game, buy a new, improved version of that game. The video game industry knows that you don’t even have to be a die hard gamer to get out your wallet for a chance to recapture the thrill of killing that zombie or discovering that master sword. Plus, there are new technologies to consider — new graphics to enjoy, new storylines to flesh out, the possibilities are endless, and the piles of gold coins keep growing.

Think of the world’s dirtiest industries and you’re probably thinking along the lines of oil or meat… but the buildings we live in, the bridges we drive on, the cars we drive in, those all involve something pretty nasty. Steel. Traditional steelmaking is a famously dirty process, but we’re here to tell you that there’s a greener way to make the thing that makes all the things.

We’ve long associated virtual reality with escaping to someplace more exciting, but the technology has never quite caught up with science fiction’s promise. But VR headsets’ emerging practical applications are a different kind of thrilling — training workers, helping in healthcare, making the workplace less stressful. All of these are reasons to celebrate, and show that VR headsets actually do have a place in every home and office, without being a means to escape them.
