It’s Netflix. The streaming service said it added 4.4 million net subscribers last quarter to top analyst predictions.

Compare that to a measly 5.5 million net subscribers for the entire first half of 2021, and it seems Netflix got its mojo back after an awkward post-quarantine period.

The star of Netflix’s summer slate? Squid Game. The gory Korean drama has become Netflix’s most popular show by far, with 142 million accounts tuning in within its first four weeks—demolishing runner-up Bridgerton’s lifetime viewership of 82 million by 73%.

• Squid Game reportedly generated $900 million in value, and it cost only about $21 million to make.
• It was also the No. 1 show in 94 different countries, showcasing Netflix’s extensive global reach.

Netflix isn’t just looking beyond borders for new customers, but also to different mediums besides TV and movies. Specifically, video games. In yesterday’s shareholder letter, Netflix highlighted that it recently a) acquired video game developer Night School Studio and b) added games to its mobile app in Poland, Spain, and Italy.

Why? Because the competition has never been fiercer. Netflix acknowledged that it competes with a “staggeringly large set of activities for consumers’ time and attention." Netflix said it recorded a 14% engagement boost when Facebook went down for several hours on Oct. 4.

But unrest is lurking beneath the surface. Some Netflix employees will rally in front of the streamer’s LA headquarters this morning ahead of a planned virtual walkout. The protest is the crest of a building wave of backlash to Dave Chappelle’s standup special The Closer, a Netflix original show that critics say is transphobic.—JW

Whether you were jabbed with Moderna, Pfizer, or another Covid-19 vaccine, you may soon be able to switch brands for your booster. The FDA could approve a mix-and-match strategy as early as tonight, when it’s expected to announce its authorization of Moderna and Johnson & Johnson boosters.

Meet “heterologous prime-boost”

Not a Transformer. It’s the scientific term for receiving two different types of vaccines. The pandemic’s putting this strategy to the test, and so far, the results are promising:

• When Europe allowed young people who got AstraZeneca’s vaccine to switch to Pfizer for their second shots, their immune systems produced more antibodies than those who stuck with one type, researchers found.
• A recent study of 50 volunteers found that people who received two J&J shots saw their antibodies increase 4x, but those who switched to Pfizer for their boosters got a 35x power-up and a 76x boost from Moderna.

Over the past year, US public companies have added the most diverse group of new directors ever, according to two new studies. Ethnic and racial minorities accounted for 47% of new directors compared to 22% the previous year, according to a study by executive search firm Spencer Stuart.

• One-third of new directors added to corporate boards between May 2020 and May 2021 were Black, up from just 11% the year prior.
• Both studies show that more than one-third of S&P 500 boards have three female directors, and roughly one-quarter of them have four. Just 10% of boards had four female directors in 2016.

The shifting makeup of boards comes as public companies face regulatory pressure to make their boards look more like America. In August, the SEC approved a rule that companies listing on the Nasdaq meet minimum diversity requirements for their boards, or explain why they missed those minimums. And a pair of recent California laws also established diversity requirements for public companies based in the state (though one of them is facing legal challenges).—MK

Stat: The place with the highest percentage of people fully vaccinated against Covid-19 in the US is not a state but a territory—Puerto Rico. 72.2% of the island’s total population is fully vaxxed. Here's a quick thread on how they did it.

Seville, Spain, will become the first city in the world to begin naming and categorizing heat waves, similar to the system already in place for hurricanes. Kicking off in 2022, the plan is part of an increasing global effort to bring more attention to heat waves as an immediate threat and symptom of climate change.

Zoom out: Climate experts and public health officials have said that naming heat waves could help make an invisible threat like heat more tangible, and allow local authorities to more easily communicate about and plan for them.

The US isn’t naming heat waves just yet, but the government is taking steps to address the dangerous effects heat has on workers (particularly, those in low-income groups). Following the hottest summer on record, the Biden administration started drafting rules on workplace heat dangers, and said the Labor Department will prioritize work inspections on days when the heat index surpasses 80 degrees.

Workplace injuries caused by extreme heat are significantly undercounted (by about 20,000/year in California alone), and extreme heat is the No. 1 weather-related killer in the country, according to the National Weather Service.—MK
