Tech giants capitalize on YouTube's loss

Twitter announced Tuesday it will make pre-roll ads available on its crowdsourced live video app, Periscope. Like Facebook, Twitter will only run pre-roll ads next to vetted content from select, trustworthy publishers.

Facebook later announced it's adding more Snapchat-like photo and and video features, including a camera button that will let users post video directly to Facebook's app.

Why it matters: Companies are taking advantage of YouTube's ad crisis by rolling out timely video updates. According to Jason Beckerman, the CEO of social intelligence firm Unified, it's a smart pitch.

"Brands are recognizing that programmatic video advertising on the internet is a risky endeavor. It's a safer bet to run video ads in closed ecosystems, like Facebook, Twitter, and Snapchat Discover, where those companies have full control to police their video content."

Antarctica's Eagle Island now has a side that's almost ice-free following this month's searing heat wave in the region, images released by NASA show.

Why it maters: "The warm spell caused widespread melting on nearby glaciers," NASA said in its report.
