What to say about fairs and the architecture of fairs?

Fairs exhibit new products which, since their number is ever increasing, try to impose themselves on potential purchasers more and more aggressively – they are all absolutely innovative, technologically supreme, and all are the right answer to an immediate or, more frequently, possible need. It is similar with fair architecture because it is also a commodity which does not have any real connection with an immediate purpose or more profound reason for existence.
