How can I watch ITVX? Is ITVX free?

All of ITV’s terrestrial channels will also be available to livestream through ITVX.

As well as the full range of ITV channels, the platform will also offer access to additional themed channels, known as “FAST” channels. Based on viewers’ preferences and programme popularity, these ever-changing “pop-up channels” will provide viewers with a personalised scheduled experience where they can choose where in the schedule they join. 

Speaking about the new platform, ITV Chief Executive, Carolyn McCall said the new streaming service will have “More content than ever before, and with a whole range of exclusive commissions.” She also added that: “ITVX is powered by a significant, streaming-first commissioning budget, and an integrated technology and data platforming providing a high quality, and more personalised viewing and advertising experience.”
