Families was a daytime soap opera produced by Granada Television and created by Kay Mellor. It followed two families; the Thompsons, based in Cheshire, England, and the Stevens, living in Sydney, Australia. It was produced and recorded at Studio 6 at Granada Studios in Manchester.

The link in the storyline was businessman Mike Thompson, who walked out on his family on his birthday and flew to Australia to be with his true love Diana Stevens, whom he had left years earlier. Unbeknownst to Mike, Diana had given birth to his son Andrew and as complications ensued over the abrupt life changes for both families, Andrew travelled to England, where he met Mike’s daughter, Amanda, by his English wife Sue, and they fell in love, not realising that they were half-brother and sister. This plot line was somewhat similar to the opening storyline of the popular Australian soap opera Sons and Daughters which had successfully aired on ITV daytime since 1983.

It was broadcast twice a week at 3.20pm with the first episode broadcast on 23 April 1990. Both episodes were also repeated on Thursday 10.40pm in the Granada TV region as part of Granada's "10.40-extra" strand. After two years, stories involving the Thompson and Stevens families—and the UK-Australian crossover angle—had run their course, with several characters either dead or left for pastures new. In their place came the wealthy Bannerman family, who were introduced during the summer of 1992, as they moved into the Thompsons' Cheshire mansion from a suburb of Manchester. In addition, some of the remaining Australian-based characters were re-located to England.
