Mobile game application entrepreneurs can offer many benefits to the U.S. economy; however, 80% of the entrepreneurs in this study stated that marketing their mobile applications was a major business challenge. Based on Schumpeter’s theory of economic development and new value creation of technological innovation, the purpose of this phenomenological study was to explore the strategies that entrepreneurs have used to market their mobile game application development businesses successfully. Twenty mobile game application entrepreneurs from northern California, who successfully sustained their businesses for 3 or more years, completed semistructured interviews. Moustakas' modified van Kaam method was used and included coding and organizing data into 5 primary themes that emerged from the analysis. The findings suggest that social media and networks are essential for marketing success, and mobile games should be innovative to ensure competitive advantages.
