Feb 7 (Reuters) - Media conglomerate News Corp beat Wall Street estimates for second-quarter revenue on Wednesday, driven by growth in digital subscriptions and a rebound in its book publishing unit.

News Corp, a part of media baron Rupert Murdoch's empire, saw a surge in digital subscriptions for its Dow Jones unit, which includes leading publications such as The Wall Street Journal, Barron's and Market Watch.

It benefited from bundling products as customers look for one-stop-shop products to consume market analysis and professional insights services.

After a slowdown during the COVID-19 pandemic, the media company is also seeing a rebound in its book publishing segment, comprising HarperCollins that has publishing operations in around 15 countries.

Revenue in the quarter ended Dec. 31 rose 3% to $2.59 billion for News Corp, compared with estimates of $2.55 billion, according to Visible Alpha data.

Excluding items, the company earned 26 cents per share, compared with estimates of 21 cents.
