Prince Alwaleed Bin Talal, the Saudi royal whose Kingdom Holding Company shares business interests with News Corp, has made a $300 million investment in Twitter. The prince, one of the world’s wealthiest men, made the investment jointly with Kingdom Holding. In a company statement, Prince Alwaleed said, “Our investment in Twitter reaffirms our ability in identifying suitable opportunities to invest in promising, high-growth businesses with a global impact.” Kingdom Holding owns about 7% of News Corp while News Corp last year reached a deal for a 9.09% stake in Kingdom and Alwaleed’s Rotana Group, a media company that includes film, TV, radio, publishing and other media interests in the Middle East. Alwaleed also recently announced plans to launch his privately owned Alarab news channel.
