In this introduction we set the stage for the chapters that make up this book. We have clustered the invited contributions in a manner that should facilitate reader’s understanding of social media within an entrepreneurial context. This vol- ume is not intended to be an exhaustive review of the literature on social media nor is it an extensive review of the role social media plays in entrepreneurial ventures. What it does explore are various aspects of how the social media in the twenty-first century has impacted entrepreneurial behaviors. We hope these chapters will stimu- late future research on social media in an entrepreneurship context.
