What country originally created the reality TV format 'The Voice'?

The reality TV format ‘The Voice’ was originally created in the Netherlands.

Its original program, ‘The Voice of Holland,’ premiered on RTL 4 on September 17, 2010. Dutch media producer John de Mol Jr. developed the concept with singer Roel van Velzen, building a singing competition around a distinctive blind-audition premise.

During blind auditions, coaches initially face away from performers and judge them primarily by their voices. A coach who wants a singer presses a button, causing the chair to turn. The format was designed to emphasize vocal ability before appearance, setting it apart from many earlier televised talent contests.

The Dutch show quickly became a success, and the format was sold internationally. Versions later appeared in the United States, United Kingdom, Australia, France, and many other markets. The country in the question refers to the format’s origin, not the country where a particular local edition aired, so the United States, United Kingdom, and Australia are incorrect.
