OTT - Over the Top Technology
I clicked through to this article because I’ve not heard of this term. Here’s how they define it:
OTT stands for Over-The-Top technologies, or any technology that aids in the delivery of audio, video and media content via the internet, without requiring users to subscribe to ,or pay for, a traditional cable or satellite pay-TV service like a Comcast or Time Warner Cable.
This has clear connections to OER and #GoOpen as they point out in the article. Thought you might be interested.
