Adds details in paragraph 3

May 11 (Reuters) - Fox Corp FOXA.O beat Wall Street estimates for third-quarter revenue on Monday, boosted by strong advertising sales in its sports and news divisions and strength in the media company's Tubi streaming service.

The company reported revenue of $3.99 billion, compared with analysts' average estimate of $3.82 billion, according to data compiled by LSEG.

"This strong performance, led by robust core advertising trends, underscores FOX's leadership in live programming, bolstered by continued strength at our leading free streaming service, Tubi," CEO Lachlan Murdoch said in a statement.
