TV18 owned and operates various national channels in separate partnerships with NBCUniversal (CNBC TV18, CNBC Awaaz and CNBC-TV18 Prime HD) and Warner Bros.

In October 2024, it merged with its parent company Network18 Group.

The group also operated a 24-hour Indian news channel in English – News18 India, targeting global audiences.

TV18 and Viacom18 had formed a strategic joint venture called IndiaCast, a multi-platform 'content asset monetisation' entity that drove domestic and international channel distribution, placement services and content syndication for the bouquet of channels from the group and third parties.

On 31 January 2018, TV18 increased its stake in the Viacom18 joint venture to 51% taking operational control.
