Skype targets businesses as growth accelerates - Yahoo! News: "Skype is adding 170,000 new subscribers every day to its 61 million person user base, up from 150,000 a day until September, when Skype announced it was to be taken over by eBay for up to $4 billion.
The company has almost doubled its number of registered users in the last six months.
A new service launched on Tuesday, Skype Groups, enables companies to set up Skype accounts for employees -- 30 percent of subscribers already use Skype for business calls.
With the new service, a person in a company can pick up the bill for all Skype users in an organization."
