text: 2010s From 4 February 2010, CGI was used in the show for the first time, with the addition of computer-generated trains.EastEnders celebrated its 25th anniversary on 19 February 2010. Santer came up with several plans to mark the occasion, including the show's first episode to be broadcast live, the second wedding between Ricky Butcher (Sid Owen) and Bianca Jackson (Patsy Palmer) and the return of Bianca's relatives, mother Carol Jackson (Lindsey Coulson), and siblings Robbie Jackson (Dean Gaffney), Sonia Fowler (Natalie Cassidy) and Billie Jackson (Devon Anderson). He told entertainment website Digital Spy, "It's really important that the feel of the week is active and exciting and not too reflective. There'll be those moments for some of our longer-serving characters that briefly reflect on themselves and how they've changed. The characters don't know that it's the 25th anniversary of anything, so it'd be absurd to contrive too many situations in which they're reflective on the past. The main engine of that week is great stories that'll get people talking." The live episode featured the death of Bradley Branning (Charlie Clements) at the conclusion of the "Who Killed Archie?" storyline, which saw Bradley's wife Stacey Slater (Lacey Turner) reveal that she was the murderer. Viewing figures peaked at 16.6 million, which was the highest viewed episode in seven years. Other events to mark the anniversary were a spin-off DVD, EastEnders: Last Tango in Walford, and an Internet spin-off, EastEnders: E20.
