Digiday Digest: Scroll speed, buy buttons and vinyl’s staying power

We rounded up the best of Digiday reporting from this week in just under a minute.

Facebook has a new formula for determining what makes a valuable impression: Scroll speed counts, and it turns out millennials are quicker with their thumbs than Gen X. They’ll register an ad 2.5 times faster, according to Facebook’s research.

Twitter, meanwhile, is adding another button alongside retweet and favorite — a buy button. It’ll show up in sponsored tweets and anywhere there’s a link to the product. So far, five brands and platforms such as Bigcommerce and Shopify representing millions of smaller brands have signed up.

Business Insider had a big week. The digital publisher got acquired by German giant Axel Springer, proving its many doubters wrong to the tune of $343 million.

Speaking of tunes, Vinyl comeback marches ever onward. It surpassed ad-supported streaming music services in the first half of 2015,  bringing in almost $60 million more, according to the RIAA.
