ITV. Instagram, which happens to be owned by Facebook, just lobbed a grenade into the YouTube camp with a new video app, and-show creation tools. Obviously, Instagram stories already let you share short, ephemeral videos, but this new platform, called IGTV, is different. It’s more like a broadcast network where all the shows are vertical video, and each can last for up to 1 hour. IGTV is launching with a bunch of well-known Instagrammers already creating content (or repurposing favorite content) and Instagram users will have access to the shows via a new core-app button. The big question is if IGTV can be as devastating to YouTube as Instagram Stories was to SnapChat. Even though the app is super-slick, my gut says no.
