For more than 50 years, a series of incarnations have graced the small screen, kicking off with Katie's family. They conveyed tradional family values for 20 years and, after a 13-year break, were followed by a group featuring actress Lynda Bellingham.
This family endured for 16 years, during which time the three children grew up. Two years ago, a third version hit the small screens aimed at capturing today's more informal family life.
