'publicly-managed' originates from the combination of 'publicly' and 'managed', where 'publicly' is derived from 'public', meaning 'of the people', and 'managed' is the past participle of 'manage', meaning 'to control or direct'.

'publicly-managed' evolved from the concept of public management, which has been a part of governance since ancient times, adapting to modern contexts.

Initially, it referred to any form of management by the public sector, and this meaning has largely remained the same in modern usage.
