the following is a list of characters that first appeared in the bbc soap opera "eastenders" in 1993, by order of first appearance. 1994 was a historic year for "eastenders", as in april, a third weekly episode was introduced. due to the programme's increased frequency, a number of new characters were introduced to the regular cast in the latter part of 1993 and early 1994. among them were the jackson family: mother carol (lindsey coulson), her four children, bianca (patsy palmer), robbie (dean gaffney), sonia (natalie cassidy), and billie (devon anderson), as well as carol's partner alan jackson (howard antony). though carol and alan were not initially married in the serial, and though alan was only the biological father of billie, the whole family took on alan's surname. the family was created by writer tony mchale. none of the actors cast as the jackson family were matched for appearance or screen compatibility. cassidy has commented, "it was all decided without doing that. i don't think it particularly mattered that none of us jackson kids looked like each other because all our characters had different dads!" carol was coulson's first major television role. various members of the family began to appear sporadically from november 1993 onwards, but in episodes that aired early in 1994, the jacksons moved from walford towers, a block of flats, to the soap's focal setting of albert square. their slow introduction was a deliberate attempt by the programme makers to introduce the whole family over a long period. the jacksons have been described by "eastenders" scriptwriter colin brake as a "classic problem family".
