EastEnders was featured for its week of episodes in 2001 which saw Zoe Slater, played by Michelle Ryan, discover her elder sister Kat was, in fact, her mother, after she had been sexually abused by her uncle.
Radio Times TV editor Alison Graham, who drew up the list, said it was an example of how soaps could "break down their boundaries and soar into new territory".

"This happened in one memorable week when the previously tiresomely boisterous Slater family revealed their dark underbelly," she said.
A moving scene from Coronation Street - "a part of the TV landscape unlike any other programme has been or will be" - screened nearly two decades ago is also singled out.
It featured recently-widowed Hilda Ogden, played by Jean Alexander, returning from her husband Stan's funeral and crying over his spectacles, which had been left behind at home.
The episode was shot after the death in 1984 of the actor who had played Stan for 20 years, Bernard Youens.
