Facebook announced last week that the criteria used to determine whether someone is a daily active visitor of its product "Watch" is by measuring whether a user spends at least 1 minute on the Watch platform per day, but Axios has confirmed that those 60 seconds do not need to be consecutive.

Why it matters: In order for Facebook to lure advertisers who typically buy ads on television to purchase video ads on Watch, it needs to convince them that the social platform's audience is just as engaged with shows on Watch. But TV networks measure a "view" of a show based on whether a show was watched for 60 consecutive seconds.

Our thought bubble: This doesn't necessarily mean that Facebook doesn't have a handful of very engaged users — it said that its daily visitors to Watch spend more than 20 minutes with the service per day — but it means that the measurement criteria is still too opaque for ad buyers at big brands to be able to buy Watch ads with the same confidence they buy TV ads.

The bottom line: There's a reason Facebook wants you to believe that Watch is pulling in TV-like engagement: It wants to sell TV-like video ads.

A Hong Kong court sentenced a group of the city's most prominent pro-democracy activists to up to 18 months in prison Friday for organizing a massive unauthorized protest in August 2019 that drew an estimated 1.7 million people, AP reports.

Why it matters: Critics say the sentences send the message that even peaceful pro-democracy activism will be severely punished. They mark a continuation of Beijing's overhaul of Hong Kong's political structure, designed to crack down opposition to the Chinese Communist Party.

J&J vaccine pause hurts its reputation

Reproduced from Economist/YouGov poll; Chart: Axios Visuals

Americans' confidence in the safety of Johnson & Johnson's coronavirus vaccine took a big dip this week after the pause in its use, per new YouGov polling, even though the risk of blood clots following the shot is extremely low, if it exists at all.

Why it matters: For the majority of people, particularly high-risk Americans, getting the J&J shot is almost certainly less dangerous than remaining vulnerable to the coronavirus.
