Microsoft is discontinuing Skype, the once-dominant internet-based phone and video service that revolutionized digital communication in the mid-2000s.

Skype will “no longer be available” to use starting in May, the company confirmed on X, telling users that their log-in information can be used on Microsoft Teams’ free tier in the “coming days.”

Fourteen years after acquiring Skype for $8.5 billion in cash, Microsoft has officially shut down the once-popular communication platform. At the time of its purchase in 2011, Skype was Microsoft’s largest-ever acquisition, and the company integrated it into key products such as Office and the now-defunct Windows Phone.

Despite experiencing a brief resurgence during the COVID-19 pandemic, Skype’s influence has steadily declined over the years. Competing services like Zoom, Google Meet, and Cisco WebEx surged in popularity, while Apple’s FaceTime and Meta’s WhatsApp also contributed to its waning relevance.

Additionally, Microsoft has focused its efforts on developing Teams, which offers many of the same features as Skype but is more tailored to modern business communication.

Skype originally launched in Estonia in 2003 and quickly gained traction as a revolutionary tool for free international calls, a significant advantage when traditional phone calls were costly. Its rapid success led to eBay purchasing the platform for $2.6 billion in 2005, but the acquisition proved unsuccessful. In 2009, eBay offloaded a 65% stake in Skype to an investor group for $1.9 billion before Microsoft took full ownership two years later.

Microsoft has yet to respond to CNN’s request for comment on Skype’s shutdown.
