Video conferencing and, more generally, real-time communications (RTC) applications have become indispensable across domains such as remote work or telemedicine, with new platforms competing for performance and market share. Much of the research to date has focused on understanding how these systems operate and perform under varying network conditions. However, the scale of the ecosystem for RTC applications beyond a handful of key players remains largely understudied and unquantified. Frameworks such as WebRTC have democratized the ability to easily extend an application to support RTC capabilities, resulting in a diverse ecosystem beyond the most commonly studied applications.
