Skype develops web-based software that allows users to make voice and video calls using the Internet. Calls are free when made Skype-to-Skype, and users can make calls to landlines and cell phones at lower rates than traditional phone services. Skype also gets revenue from voice mail and other services, and offers a platform for business communications for small and midsized firms. Skype was acquired by Microsoft for $8.5 billion in 2011.
