Tech companies dominated the 2010s, with the FANG stocks (Facebook, Amazon, Netflix, Google) helping the S&P 500 return more than 350% over the course of the decade. The index would have done even better had it included Domino's Pizza, which is also a tech company.

Why it matters: These companies don't look like the tech firms of earlier decades. They don't manufacture computer hardware; neither do they sell software. They don't even make high-tech planes, like Boeing, or high-tech cars, like Tesla.

Former HBO boss Richard Plepler has secured a five-year exclusive deal with Apple to produce feature films, documentaries and original series for Apple TV+, his spokesperson confirmed to Axios.

Why it matters: The deal brings authority to Apple's fledgling content efforts, and gives Plepler a powerful platform to continue his influence as one of the entertainment industry's top producers and talent magnets.

Google Health developed an artificial intelligence system that can identify cases of breast cancer from mammograms more accurately than radiologists according to an international study, the Financial Times reports.

Why it matters: It's the latest example of how AI could improve early detection of diseases and reduce both false positives and false negatives diagnoses.

Starting today, Californians can find out what data certain companies have collected about them, and even ask for it to be deleted, under the new California Consumer Privacy Act.

Why it matters: The law covers residents of the most populous state, but it also has national repercussions. Some companies like Microsoft have already said they'll be extending the practices required under the law to all their customers and users. And other states tend to follow California when it introduces firm rules that don't exist on the federal level.
