Inflatables are an obvious choice for space vehicles and satellites, a small sized payload than can be inflated once up, yet for some reason they aren’t the norm.
The first passive communications satellites were inflatable spheres, such as the Echo series, which mylar was developed for, and early prototypes for space stations were inflatable. More recently, funding for the inflatable replacement for the habitat unit on the space station was cancelled and a private company Bigelow Aerospace is now the pioneer in the field, having successfully launched an inflatable unit.

The Mylar Echo satellites didn't stay up long, becuase the suns heat would deform them and slow them down. The answer was this system where a helium inflated plastic sphere would expand a signal reflecting hollow mesh, with the plastic dissolving under the suns rays. The mesh could then stay up for 11 years or so. (via)

NASA developed mylar for the Echo program. These were inflatable passive communication satellites, i.e. signals were bounced off them to reach places on the other side of the earth. (via)

After NASAs inflatable habitat funding was cancelled a private firm, Bigelow Aerospace launched the first inflatable habitat prototype, aboard a converted missile, in 2006. Genesis 1 is 14ft by 8ft. (via)
