Hayley's Diary was a two-week series of photo-essays, mini-episodes and a behind-the-scenes extra on the official Coronation Street website to tie in with the storyline of Hayley Cropper coming to terms with her terminal cancer by achieving all of the items on her "bucket list" and keeping a journal of her achievements. The diary was first mentioned by her in Episode 8225 (30th September 2013) and the first segment of the feature was released as that episode completed transmission at 8.58pm. Thereafter, there were thirteen additional entries in the run-up to Episode 8236 (16th October 2013) when Roy and Hayley visited Blackpool, three of which included specially-filmed mini-episodes, the latter all being reference in the standard episodes transmitted on the same day. The releases were all produced by Alan Toner. and starred Julie Hesmondhalgh as Hayley and David Neilson as Roy.
Hayley gives the reasons for writing a diary - the first she's ever composed - which are to leave a memento for Hope Stape and Ruby Soames to read when they get older in the hope that they, "might remember the funny lady in the red anorak, who looked after you every now and then." The first item ticked off for her was getting Roy to sing karaoke on his birthday at the Rovers which, she admitted, was more him speaking the lines to I've Had The Time of My Life as she sang but he did get a standing ovation. Other contributors were Fiz Stape and Tyrone Dobbs singing Summer Loving' and six songs from Mary Taylor (though none of these were shown in Episode 8218 (20th September 2013) which featured the party itself).
