Origin & History
Origins and dates here are approximate summaries. Many idioms have disputed or unknown origins, and not every date has been checked against a historical dictionary, so treat specific dates and stories as a starting point rather than a citation.
Puppeteers kept control with strings, so the phrase means absence of controls.
Became popular in mid-20th-century advertising.
