As the 1957 Broadcasting Act remained in force, ZBC inherited RBC's state monopoly on broadcasting, remaining accountable to the country's Minister of Information. In a reflection of the new ZANU PF government's political leanings, Robert Mugabe, previously described only as "a terrorist leader", was now described as "Comrade Prime Minister". In addition, most of the white staff left ZBC after independence, and many of the black staff who replaced them had previously worked in for radio services operated by the nationalist movements from exile in Zambia and Mozambique.
