News Corp has announced two purchases - of a financial daily and a book publisher.
The 'books and media' segment of Houghton Mifflin Harcourt will be operated by subsidiary HarperCollins Publishers, bringing to News an extensive backlist and a "history of strong profitability", the company says.
Investor's Business Daily - which News will acquire from O'Neil Capital Management for $275 million - will be operated by Wall Street Journal publisher Dow Jones, another subsidiary.
Established in 1984, IBD is reported to have been experiencing "double-digit revenue growth" in recent years, more than 90 per cent of it coming from digital.
