Over-the-top (OTT)

Over-the-Top, or OTT, is a method of delivering content over the internet, without requiring a cable or satellite subscription. This includes services like Netflix, Hulu, and Amazon Prime Video. It can be accessed on many devices, including mobile devices, tablets, computers, and connected TVs.

OTT, for example, is watching Netflix on a mobile device. But, watching Netflix on a smart TV is Connected TV (CTV).
