Microsoft and Time Warner, both giants in their respective
fields, announced in April that they, together with ContentGuard,
had purchased most of the stake held in the firm by its original
owner, Xerox.
ContentGuard is a leading provider of DRM technology, which
controls how copyrighted digital content, such as DVDs or software,
can be viewed, used, or abused.
Microsoft already held a stake in the firm, and commentators saw
its increased holding in the company as a sign that Microsoft was
keen to gain a share of the digital music and movie market.
As both Microsoft and Time Warner are industry leaders, the
joint acquisition requires approval from EU competition regulators.
The decision had been expected on Monday.
