Like the family members who drop in unannounced over the festive period, armed with a smile and a carrier bag in which to take home leftover food from the table, television has formed a habit of producing the occasional passing by of a character or a family that the audience once took to their hearts and giving them the briefest glimpse of what they are up to, showing the fan what they look like now in the hope that it may spark some interest in the art of revival.
