Modern multi-arts festivals face the constant organizational challende of reinventing themselves on a regular basis. One oft-heard "rule of thumb amongst festival managers says that unless they breathe new life in to their festivals every 3 to 4 years, theirr festivals will likely experience an inevitable decline of visitors. Innovative technologies readily adopted by ffestival organizations are applied to areas, such as sponsorship fulfillment, visitor communications, tecketing, as well as security and crowd control. The purpose of this chapter is to examine how the particpatory groups of certain festivals ensure their annual renewal, perhaps better than introducing innovations into the festival. Using data drawn from studies and case material of long-term festivals and carnivals, the study suggtest that new festival technologies have had to date, a limited impact on development of multi-arts festivals, The author argues that mincroeconomic principles related to festival participation are better predictors of truly innovative and renewable festivals.
