Siemens AG, who has been a Disney Parks corporate sponsor since 2007, has chosen to not renew their deal.
Siemens sponsored Spaceship Earth and IllumiNations: Reflections of Earth at Epcot, as well as “it’s a small world’ at Disneyland Park. In the past, they also sponsored the Osborne Family Spectacle of Dancing Lights (as Sylvania, a company they own) and their technology was used to create the Radiator Springs Racers attraction at Disney California Adventure and used elsewhere in the parks.
The end of the sponsorship comes amidst rumors that Siemens offered Walt Disney World a new monorail fleet for free so long as they were company branded, but Disney reportedly declined.
In the midst of a rather large overhaul of Epcot, this change does make the future of Spaceship Earth a lot more interesting. It was already assumed that IllumiNations: Reflections of Earth would be going away, but this change makes the end of that show all the more likely.
