LEADING THE DAY: Things are heating up as Google and Facebook battle for control of the social Web. The Daily Beast’s Dan Lyons reported that Facebook paid Burson-Marsteller, a top PR firm, to promote a story claiming that Google is invading user privacy by gathering information from users’ social networks. The report says a Facebook spokesman confirmed the company is behind the campaign, because it objects to Google’s practices and is upset that Google is using Facebook data without permission.

On Monday, USA Today accused the PR firm of running a whisper campaign against Google.

Software piracy on the rise in developing markets: A new study from the Business Software Alliance found that software piracy is on the rise in emerging markets and now accounts for more than half of all software theft. BSA President and CEO Robert Holleyman said in an interview that this development threatens the economy beyond the software industry. Software theft, Holleyman said, lowers the operating costs in places with high piracy rates such as China, threatening businesses that observe software laws in places like the U.S., where piracy rates are lower. The group estimates that $59 billion of software was stolen in 2010, 14 percent more than the previous year.
