With the advent of these fan-consumers (as opposed to fan-creators), dōjinshi became demand-driven publications. Greater competition gradually fostered rising standards of quality, which in turn attracted more circles and buyers. Higher sales shrank production costs and boosted profits, which could then be reinvested in the dōjinshi themselves. Small printing companies, many of which had begun in the minikomi (microcommunication) boom of the early 1970s, were able to use the profits derived from greater demand for their services to modernize their equipment, lowering production costs further and enabling them to construct their production schedules around each Comike.8 Additionally, lower printing costs freed smaller groups from the dependence on bigger groups, which often had strict rules on content and style to avoid conflict among their many members. Having lost their raison d'être, these big clubs and circles gradually faded away, leaving dōjinshi creators to produce stories they liked, in the manner they liked.9
