2016 - WeChat launched Enterprise version. Skype should better react

Chinese messenger WeChat launched its free office chat app, WeChat Enterprise.For now it's only available in Chinese via apps for iOS, Android, Windows, and OS X. WeChat Enterprise includes a number of features that are familiar territory to those who have used business chat apps. But it also has some welcome innovations. The service can essentially replace group email, and make quick chats between colleagues easier. It has useful add-ons like the ability for an employee to mark when they are on a break, hold group voice/text chats, and allows for companies to build in specific features like automated forms for reimbursements, vacations, and the like.

2010 - Cisco's top manager to become Skype CEO to compete with WeChat

Tony Bates (Tony Bates, the new Skype CEO)
Recently, we wrote that Cisco could buy Skype. These rumors appeared since it was found out that Skype and Cisco are conducting negotiations. But probably, it was not Cisco trying to buy Skype, but Skype owners trying to get Cisco's top manager Tony Bates to become Skype's exec. Today, Tony Bates, who was a senior Enterprise VP at Cisco, replaced Josh Silverman as Skype CEO. Most likely, this means that Skype will not be sold to Cisco or any other company and go to IPO to become a public company. (If Cisco was going to buy Skype, it would be logical to appoint CEO after the acquisition). Additionally, this means that Skype's new priority will be the enterprise market, that Bates perfectly knows. That is where the Skype owners are going to make money.
