What’s Up? (July 14-20)

Stranger Things

Netflix lost more than 10 percent of its stock market value after the company said it had lost 126,000 subscribers in the United States last quarter — its first-ever such decline. The service also reported weak growth in overseas markets. The slide comes as competitors like Disney, AT&T and NBCUniversal are starting streaming services and, in some cases, taking their own hugely popular shows with them, like “Friends” and “The Office.” Another reason for the weak performance: This was the quarter that Netflix’s price increases went into effect.

Facebook Coin Scrutiny

Members of Congress grilled Facebook over its plans for a digital currency, Libra. The company is hoping to provide financial services without being treated, and regulated, as a bank. Lawmakers said they weren’t sure they could trust the company enough to let that happen. (An astrological coincidence? The digital currency exchange founded by the Winklevoss twins — they’re the ones who fought a legal battle with Mark Zuckerberg over the ownership of Facebook — is called Gemini.)
