NEEDHAM, Mass.–(BUSINESS WIRE)–#IDCTracker–The worldwide Unified Communications & Collaboration (UC&C) market grew 29.2% year over year and 7.1% quarter over quarter to $13.1 billion in the fourth quarter of 2020 (4Q20) , according to the International Data Corporation (IDC) Worldwide Quarterly Unified Communications & Collaboration QView. Revenue growth was also up an impressive 24.9% for the full year 2020 to $47.2 billion.

How business was conducted changed dramatically in 2020 due to COVID-19, driving companies of all sizes to consider and adopt scalable, flexible, cloud-based digital technology solutions (e.g., Unified Communications as a Service or UCaaS) as part of their overall integrated UC&C solution. Vendors and service providers also saw exponential growth in the number of video and collaboration end users in 2020. In 2021 and beyond, IDC expects worldwide UC&C growth will be driven by customers across all business size segments (small, midsize, and large) with interest especially in video, collaboration, UCaaS, mobile applications, and digital transformation (DX) projects.

Some UC&C market specifics include the following:

  • Hosted Voice/UC Public Cloud (UCaaS) grew 26.1% year over year and 6.8% sequentially in 4Q20 to nearly $4.6 billion in revenue. For the full year 2020, public cloud UCaaS revenue increased 21.2% to $16.4 billion.
