The widespread availability of the Internet has led to a new kind of certification for websites. Website certifications exist to certify the website's privacy policy, security of their financial transactions, suitability for minors, among many other acceptability characteristics. In broadcast engineering, transmitters and radio antennas often must by certified by the country's broadcasting authority. In the United States, this certification was once called "type acceptance" by the Federal Communications Commission (FCC), and applied to most services except amateur radio due to its inherent homebrew nature. Today the FCC requires all testing of transmitters and antennas to be performed in a laboratory accredited to ISO 17025, with that laboratory being part of the overall organization that houses the Product Certification Body (TCB).
