Media entrepreneurship comes in many forms due to the kinds of ventures it encompasses. Media firms include those operating in news and content, music, film, communication technology, e-commerce, and cloud and storage businesses. Typical media entrepreneurship ventures are media and communication start-ups (e.g., Shazam, a sound and music identification app); various businesses setup on social media and digital platforms (e.g., websites of clothes firms); news and infotainment websites (e.g., HuffPost); e-commerce stores and other electronic vendors (e.g., personal and business profiles on eBay or Amazon); advertising websites (e.g., car buy-and-sell websites, car-sharing platforms); and user-generated content platforms (e.g., blogs, forums). This entry discusses the process, challenges, and impact of media entrepreneurship.
