Digital
From 5 March 2006, digital viewers were able to press the red button to access an enhanced TV service called Smile Backstage which allows them to seamlessly switch between live action in the studio and behind-the scenes, using the left and right buttons on their TV remote control. Most of the action backstage is one of the presenters hanging out with Smile's special guests and doing additional challenges, playing games and chatting. Smile Backstage was the first time that an interactive TV stream-switching application had been used on a live broadcast at the BBC. Previously, viewers could also watch an extra seven minutes of programme content after the end of the main show. Smile won the Interactive Award at the Children's BAFTAs in November 2005.
