Facebook's recent shifts away from viral content, news, and video are already having an impact, said CEO Mark Zuckerberg as part of the company's latest quarterly report.

Why it matters: It's been a year of reckoning for the social network, which has had to deal with its influence over people's news diet and sharp criticism over its ability to exploit human psychology for attention. These forces led Facebook to change the newsfeed algorithm to focus more on content posted by friends rather than publishers.

Already last quarter, we made changes to show fewer viral videos to make sure people's time is well spent. In total, we made changes that reduced time spent on Facebook by roughly 50 million hours every day. By focusing on meaningful connections, our community and business will be stronger over the long term.
— Facebook CEO Mark Zuckerberg

The bottom line: Facebook's stock price is down nearly 5% in after-hours trading.

The Food and Drug Administration on Saturday issued an emergency use authorization for Johnson & Johnson's one-shot coronavirus vaccine.

Why it matters: The authorization of a third coronavirus vaccine in the U.S. will help speed up the vaccine rollout across the country, especially since the J&J shot only requires one dose as opposed to Moderna and Pfizer-BioNTech's two-shot vaccines.
