Skype group video calling supports up to 10 people at once, same as Google Hangouts. However, ooVoo supports up to 12 people at once.
Microsoft has built Skype support into Outlook.com making it easier for its users to use Skype for messaging. Like Google Hangouts, Skype requires a web plugin to work in a browser. Alternatively, users can download Skype for Windows or Mac to make and receive messages, calls, and video chats.
