The technology is in field since year 2004. It has received multiple awards at trade shows and by today has become the dominating solution in new projects worldwide. As of 2016 it is on air in about 6,000 broadcast radio studios in USA, Canada, Australia, and many other countries in Europe, South America, Asia, Africa. It is being chosen by radio stations of all profiles and budgets, from small college radios to big public and private networks, from very simple to technically most demanding projects. Besides the Telos Alliance, it is adopted and included into products by tens of industry partner companies.
