Instagram surprised everyone this week with the release of IGTV - a stand alone long-form video application for content creators and consumers. The Facebook Marketplace is a feature of the social media giant that is often under reported on but has some great benefits for buyers and sellers of goods. Following their acquisition of Time Warner, AT&T released a privacy policy update. The FAQ page is one of the most comprehensive pages out there. And finally, AppNexus has been bought by AT&T as the telecom giant pushes into digital advertising to compete with the likes of Facebook and Verizon.
