It was first broadcast on the Seven Network on 18 March 1985. It was created by TV executive Reg Watson, who proposed the idea of making a show that focused on realistic stories and portrayed adults and teenagers who talk openly and solve their problems together. Seven decided to commission the show following the success of Watson's "Sons and Daughters", which aired on the network. Although successful in Melbourne, "Neighbours" underperformed in the Sydney market and struggled for months before Seven cancelled it. The show was immediately bought by rival network Ten. After taking over production of the show, the new network had to build replica sets because Seven destroyed the originals to prevent its rival from obtaining them.
