MPEG LA has allowed the free use of H.264 technologies for streaming Internet video that is free to end users, and Cisco Systems <https://en.wikipedia.org/wiki/Cisco_Systems> pays royalties to MPEG LA on behalf of the users of binaries for its open source <https://en.wikipedia.org/wiki/Open-source_software> H.264 encoder.
