At the Innovations Day on Communication Networks 2005, Siemens and GRUNDY Light Entertainment – a company belonging to the UFA Group, Germany’s largest supplier of television entertainment programming – presented a new dimension in entertainment by connecting television with broadband fixed and mobile networks. In the first experiment of its kind anywhere, both companies recently succeeded in linking in viewers live either from home or out and about to let them participate in a game show. The viewers called in during the show and were "beamed into the television studio" via video telephony.
