2016 - Skype for Business is available on Mac to fight Cisco Spark

Microsoft announced the launch of Skype for Business for Mac Preview  – the business-focused version of Skype’s communications services aimed at a commercial client base. I.T. administrators and individuals can sign up to test the new desktop software, which introduces features like Outlook integration, additional security, and calls that allow for up to 250 people versus Skype’s 25 max. However, Microsoft says invites will roll out first to I.T. admins before becoming more broadly available.

2003 - Microsoft launches Web conferencing service Live Meeting to strike back at Cisco Spark

Microsoft unveiled its Web conferencing service called Live Meeting. It'ss based on technology the Redmond, Wash., software maker obtained when it acquired PlaceWare in early 2002. Live Meeting, like similar services on the market, is largely designed to enhance conference calls with Web content. Participants log into a central Web site, where they can then concurrently view a presentation, exchange notes or ask questions through chat software, and collaboratively edit documents. A number of companies use it for remote training seminars. Live Meeting, an essential part of Office, marks a change in the overall sweep of the product suite. For years, Office has been synonymous with the bundle of desktop applications such as Word or PowerPoint that comes with corporate computers. In the future, Office will encompass a broader collection of applications and services. With Live Meeting, for instance, customers don't download any new software, and no extra software is included in the desktop suite. All the software needed to conduct Web conferences--except for a standard browser--will remain on Microsoft servers.
