The first transmission was launched on March 24, 1966. Levi Eshkol, the Israeli prime minister, pressed a symbolic button to mark the beginning of the transmission. Lord Jacob Rothschild delivered a speech on behalf of the Rothschild Fund. The then-called Instructional Television Trust opened its regular transmission with televised broadcasts of Mathematics, Biology and English classes. 60 TV sets were distributed to 32 schools to receive the first broadcasts and comment on their quality. From the early 70's and until the early 90's it was known as the "Instructional Television Centre".
