WarnerMedia pulled back the curtains on HBO Max earlier this month, unveiling its programming slate, which will include 10,000 hours of content ranging from classic comedy Friends to new original shows.
In addition to HBO content, the service spans a range of brands including TNT, TBS, CBS, the CW, Cartoon Network and others.
Earlier this week, WarnerMedia handed a 10-episode straight-to-series order for a reboot of teen drama Gossip Girl.
WarnerMedia chairman Bob Greenblatt said: “Kevin has assembled a stellar creative team for new originals and acquisitions that will make our HBO Max service second-to-none. With these originals and the full force of the vast WarnerMedia portfolio, including the might of HBO, I couldn’t be more proud of the content we are bringing together across this company that will appeal to everyone in the household.”
