In 2004, Simon Faithfull was commissioned to do a live event by The Arts Catalyst for its Artists Airshow. He decided to launch a weather balloon with a chair attached to it. The audience could follow the live video feed on a large screen. A typical art project.
In 2009, the advertising agency Grey London did The Space Chair Project for their client Toshiba. They also launched a chair with a weather balloon, except that they used HD cameras to create the highest HD TV ad in the world. But somehow they don’t mention Simon Faithfull anywhere …

Update: According to this article, Simon was part of the team who did the ad.
