The 21st Century Communications and Video Accessibility Act (CVAA) applies to:

The 21st Century Communications and Video Accessibility Act (CVAA) is designed to ensure that individuals with disabilities have full access to modern communication technologies. By encompassing all entities covered by FCC regulations, the CVAA mandates compliance from a broad range of telecommunications and media organizations, not just a specific subset like public broadcasters, hardware providers, or television broadcasters.

This broad applicability helps to create a more inclusive environment by requiring various stakeholders—including internet service providers, telecommunications companies, and cable operators—to implement accessibility features in their products and services. By doing so, the act addresses the diverse ways people communicate in the 21st century, ensuring that advancements in technology do not exclude individuals with disabilities from accessing vital communication platforms.

The other options are limited in scope and do not reflect the comprehensive reach of the CVAA as it applies to all regulated entities, thereby making them incomplete in addressing the act's intentions and requirements.
