When Sputnik went around the planet in 1957 the earth became enclosed in a man-made environment and became thereby an “art” form. The globe became a theatre enclosed in a proscenium arch of satellites. From that time the “audience” or the population of the planet became actors in a new sort of theatre. Mallarmé had thought that “the world exists to end in a book.” It turned out otherwise. It has taken on the character of theatre or playhouse. Since Sputnik the entire world has become a single sound-light show. Even the business world has now taken over the concept of  “performance” as a salient criterion.
