Leading into 2015, there was concern that the rise of easy-to-use tools to create and distribute video games could lead to an oversupply of video games, this was termed the "indiepocalypse". This perception of an indiepocalypse is not unanimous; Jeff Vogel stated in a talk at GDC 2016 that any downturn was just part of the standard business cycle. The size of the indie game market was estimated in March 2016 to be at least $1 billion per year for just those games offered through Steam. Mike Wilson, Graeme Struthers and Harry Miller, the co-founders of indie publisher Devolver Digital, stated in April 2016 that the market in indie games is more competitive than ever but continues to appear healthy with no signs of faltering. "Gamasutra" said that by the end of 2016, while there had not be any type of catastrophic collapse of the indie game market, there were signs that the growth of the market had significantly slowed and that it has entered a "post-indiepocalypse" phase as business models related to indie games adjust to these new market conditions.
