Masterclock's® predecessor was founded by William (Bill) Clark in 1986 to build automation systems for the Radio and TV industries. Masterclock® itself was incorporated as an entity in 1994. Starting with a two person operation in the proverbial home garage it has grown into a successful enterprise doing multi-million dollars in business throughout the world.

The company's first product was the TCR100 time code reader card developed in 1986 to synchronize IBM personal computers in Radio/TV broadcast networks automation systems. Over the years Masterclock® has introduced an array of products to meet the demand of customers engaged in many different types of activities where correct and accurate time is critical; they are among the world's most demanding and time sensitive users.
