The content of the channel, much of which is drawn from the US station, comprised predominantly original non-fiction programming covering a range of historical, scientific and cultural subjects.

Test transmissions for the new services began with the addition of HD and subsequently SD broadcast capacity on the Astra 2G satellite in late 2018.

The channel was officially made available on 12 February 2019.

On December 15, 2022, it was announced that the channel would be closing on January 6, 2023 after nearly four years on air.

Its programming shifted online to other Paramount Global presences, including Paramount+, My5 and Pluto TV.
