Wired: Instagram is launching a video channel — a heavily curated, 24-hour deep dive into the very best videos Instagrammers post. Americans can pull up the app, click on the explore tab, and land in an immersive video viewer that will allow them to watch programming from all over the country. Instragram is becoming a formidable news service rivaling the Internet’s original newswire, Twitter. But Instagram isn’t Twitter’s only rival; Snapchat reports more than 100 million daily active users.
