Radio 702 (first called Channel 702 ) was originally based on the US inspired top 40 music format pioneered by LM Radio broadcasting to South Africa from Mozambique, and Swazi Music Radio (SMR) which broadcast from Sandlane in Swaziland with studios in Johannesburg. SMR was established and operated by the brothers Isaac (Issie) and Nathaniel (Natie) Kirsh, the founders of Primedia which owns Radio 702. Many of the early presenters on SMR cut their teeth in broadcasting at LM Radio or worked there, like Gary Edwards, John Berks and Frank Sanders. LM Radio became Radio 5 (now 5FM)
