HBO Could Use a Hit. Enter the Dragons.

The dragons are back. And not a moment too soon.

On Sunday, “House of the Dragon,” the “Game of Thrones” prequel series, will return to HBO for its second season. The show became a bona fide hit in its first season, in 2022, and helped kick off a torrid winning streak for the network that included the beloved sophomore season of “The White Lotus”; the premiere of a new hit, “The Last of Us”; and the decorated final season of “Succession.”

But over the past year, HBO has encountered a fallow stretch — unusual for America’s pre-eminent premium television network.

There have been disappointments (the music drama “The Idol” and the Kate Winslet-starring limited series “The Regime,” for instance), and delayed premieres because of the double Hollywood strikes last year. According to one widely used industry metric, Max, the 13-month-old streaming service that houses HBO’s shows, has plateaued during that time. One high-ranking executive at Warner Bros. Discovery, HBO’s parent company, chalked up Max’s slow start to “probably the lightest content slate we’ve ever had.”

HBO’s one-year slowdown could be underscored when Emmy nominations arrive next month, usually a cause for celebration for the network. But in contrast to previous years, shows from HBO and Max will not be favorites in some of the major categories, including drama, a category that HBO dominated at the most recent Emmys.

According to some award forecasters, HBO could finish third among networks in total nominations, which would be its lowest ranking since 1996.

HBO executives acknowledged that they were anticipating reduced award recognition this year. But they said they were looking to the months ahead, starting with this weekend.
