Nielsen will add Instagram to its Social Content Ratings® (SCR) platform, which measures social engagement with TV shows. Nielsen already measures Facebook and Twitter engagement with TV shows.

Why it matters: Ratings do not always equal social engagement. SCR ratings help brands and networks understand how their content performs across platforms, which is important given that roughly 70.3% of the total U.S. adult population will regularly use another digital device while watching TV, according to eMarketer.

Go deeper: As Axios noted when we reported Nielsen's first social content ratings ever, "TV measurement is going to have to change to account for the role digital plays in television consumption and expanding television's reach to different audiences, instead of totally eating it."

With President Trump planning to nominate his third Supreme Court justice nominee by next week, key Republican senators are indicating their stance on replacing the late Justice Ruth Bader Ginsburg just over six weeks out from Election Day.

The big picture: Senate Majority Leader Mitch McConnell (Ky.) has vowed that "Trump’s nominee will receive a vote on the floor of the United States Senate." But Sen. Lisa Murkowski (Alaska) told Alaska Public Media, "I would not vote to confirm a Supreme Court nominee. We are 50 some days away from an election."
