(Reuters) - Warner Bros Discovery missed first-quarter revenue estimates on Thursday, weighed down by a lack of big box office hits from its studios and weakness in its traditional TV business as consumers continued to abandon cable for streaming.

Like others in the media business, Warner Bros Discovery is losing thousands of cable TV subscribers each year, putting pressure on the company to consistently produce hit content and boost profitability in its streaming business.

The threat of U.S. tariffs on foreign-made films has also added to the headaches of an industry whose biggest-budget films are often produced across several continents.
