text: The name of the unified city was Tel Aviv until 19 August 1950 , when it was renamed Tel Aviv-Yafo in order to preserve the historical name Jaffa . Tel Aviv thus grew to 42 k. In 1949 , a memorial to the 60 founders of Tel Aviv was constructed .
simplified: Tel Aviv-Yafo is the official name of the city , but it is almost always called Tel Aviv .
