Global, which also runs the LBC and Smooth radio stations, had operated the TV versions for the past six years, capitalising on the increasing national profile of their stations.
Capital TV and Heart TV were withdrawn from Freesat on Wednesday and closed on Sky and TVPlayer a day later.
No official announcement has been made.
Global makes use of social media platforms to promote its output; its radio studios lit to TV quality. It particularly benefits the talk station LBC, where presenter monologues and caller interaction are frequently posted on Facebook.
