Sydney-Principal Big Brother sponsors 3 mobile and KFC are leveraging their alignment with the hit Network Ten franchise through integrated website sponsorships. Season seven of the reality show launches on April 22. 3 mobile will again be a major sponsor across broadcast, online and mobile phones. KFC is utilizing the Big Brother website to leverage all KFC on-air activity as well as a platform to launch and drive its KFC Twister promotion. Rated as the No. 1 Australian TV programme website last year, the site attracted 208 million page viewers (up from 170 million in 2005), and at least 1.1 million unique browsers visited the site each month. The website has been rebuilt by Endemol Southern Star and Ten for the 2007 series to provide more intuitive navigation, more video and greater interactivity, including a new in-built instant messenger product.
