Google has agreed to a series of audits on its video advertising metrics by the Media Rating Council (MRC), which serves as the effective watchdog for advertising measurement across platforms. MRC will audit three measurement companies that work with Google to measure how often and how much of their YouTube video ads are viewed by actual people.

Why they're doing this: Google doesn't want to lose the trust of ad buyers, especially on YouTube, which eMarketer estimates will add 20% in ad revenue in 2017. Because Google and Facebook have been bullish about releasing proprietary metrics to third-party data measurement companies, ad buyers have been wary about trusting the data they get from third-party vendors.

Why it matters: Google and Facebook have an effective "duopoly" over digital ad revenue, eating up more than 90% of all new ad dollars. In light of this, both companies have experienced heightened pressure to re-assure ad buyers about the quality of the data they release to third-party measurement companies. Earlier this month, Facebook agreed to an internal audit by MRC after they admitted to misreporting video viewing data to publishing partners.

Schools face an uphill battle to reopen during the pandemic

Illustration: Aïda Amer/Axios

President Biden's plan to accelerate the reopening of K-8 schools faces major challenges from a still out-of-control pandemic and more contagious coronavirus variants.

Why it matters: The longer American kids miss in-person schooling, the further they fall behind. But the uncertain state of the science on the role young children play in the pandemic continues to complicate efforts to reopen schools.

Focus group: Former Trump voters say he should never hold office again

"Relief" is the top emotion some swing voters who used to support Donald Trump say they felt as they watched President Biden's swearing-in, followed by "hope."

Why it matters: For voters on the bubble between parties, this moment is less about excitement for Biden or liberal politics than exhaustion and disgust with Trump and a craving for national healing. Most said Trump should be prohibited from ever holding office again.
