Adds details

Feb 5 (Reuters) - News Corp NWSA.O beat Wall Street estimates for second-quarter revenue on Thursday, bolstered by growth in its Dow Jones, digital real estate and book publishing units.

The results indicate that growth in high-margin digital subscriptions at its Dow Jones division, which includes The Wall Street Journal, is helping the media company weather economic uncertainty and a choppy advertising market.

The Dow Jones segment's revenue increased by 8% to $648 million from the previous year.

The performance was also bolstered by a recovering property market, which lifted revenue at its digital real estate services segment by 8%.

News Corp's book publishing segment, which consists of HarperCollins, saw revenue rise 6% to $633 million in the quarter.

The company reported total revenue of $2.36 billion for the quarter, compared with analysts' average estimate of $2.29 billion, according to data compiled by LSEG.
