In October 2014, Paramount partnered with Google to promote Interstellar across multiple platforms. The film's website was relaunched as a digital hub hosted on a Google domain, which collected feedback from film audiences, and linked to a mobile app. It featured a game in which players could build Solar System models and use a flight simulator for space travel. The Paramount–Google partnership also included a virtual time capsule compiled with user-generated content, made available in 2015. The initiative Google for Education used the film as a basis for promoting math and science lesson plans in schools.
