Over-The-Top (OTT) video delivery uses third-party content delivery networks to stream video over the internet. YouTube is a popular free OTT service, and the proliferation of internet-connected devices has increased complex, multi-screen video consumption. As a result, video delivery is shifting from pay TV operators and set-top boxes to content owners and many different devices. For pay TV operators, OTT poses a threat as subscribers may opt for OTT services instead. To remain relevant, pay TV operators should acquire content, ensure high quality of service, expand beyond set-top boxes with OTT apps, and provide a unified subscription for viewing on multiple devices and screens.
