Posted by Eric Losier on Apr 18, 2018 2:47:03 PM

 

Cisco Spark, the app-centric, cloud-based collaboration, and communications suite is being re-branded as Cisco Webex Teams, while WebEx is to be re-branded as Webex Meetings. 

Speaking April 18th at the Cisco Collaboration Summit 2018 show in Phoenix, AZ., Rowan Trollope, Senior Vice President and General Manager of Cisco's Applications announced the name change as part of its new Webex portfolio of products. 

Webex will be repositioned as the umbrella name for the company's entire collaboration portfolio consisting of Webex Meetings (formerly WebEx), and Webex Teams (formerly Spark). 

Now before we continue, yes it is Webex, not WebEx, the removal of the capitalized “E” is part of the new look and feel. 

In this article, we will highlight some of the essential aspects of this re-branding including reasons behind the changes. We will also discuss some of the new features and functionalities of both Webex Meetings and Webex Teams.
