This study examines the impact of the 2019 departure of Fortnite streamer Richard Tyler \u201cNinja\u201d Blevins from Twitch to Mixer. Using a quasi-experimental research design, we find that Ninja\u2019s exit led to a 20.4% decline in content production from peer creators, which reveals a critical spillover effect on content supply. Contrary to concerns that creators would abandon Twitch entirely, our findings suggest that they instead downsized their output. Notably, streamers with diversified content portfolios and larger followings were more resilient to the star\u2019s departure. For platform managers, these results highlight the strategic importance of retaining top creators to sustain both direct and indirect content supply. Managing star departures effectively is crucial for ensuring a stable content ecosystem. Efforts to counteract negative spillovers may include incentivizing content diversification and mitigating reliance on individual stars, for instance, through enhancing visibility and monetization opportunities for midtier creators. Strengthening platform loyalty through long-term incentives might also reduce the risk of sudden exits.<\/jats:p>","DOI":"10.1287\/isre.2023.0367","type":"journal-article","created":{"date-parts":[[2025,5,14]],"date-time":"2025-05-14T09:44:12Z","timestamp":1747215852000},"page":"568-583","source":"Crossref","is-referenced-by-count":3,"title":["Star Wars: An Empirical Study of Star Performer Turnover and Content Supply on Multisided Streaming Platforms"],"prefix":"10.1287","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3090-4559","authenticated-orcid":false,"given":"Jens","family":"Forderer","sequence":"first","affiliation":[{"name":"Business School, University of Mannheim, 68161 Mannheim, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2633-9518","authenticated-orcid":false,"given":"Dominik","family":"Gutt","sequence":"additional","affiliation":[{"name":"Rotterdam School of Management, Erasmus University Rotterdam, 3062 PA Rotterdam, Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0772-7814","authenticated-orcid":false,"given":"Brad N.","family":"Greenwood","sequence":"additional","affiliation":[{"name":"School of Business, George Mason University, Fairfax, Virginia 22030"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"109","reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1093\/qje\/qjac038"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.5465\/annals.2014.0079"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1287\/mnsc.2015.2266"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1515\/9781400829828"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1111\/j.1756-2171.2006.tb00037.x"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1162\/qjec.2010.125.2.549"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jfineco.2022.01.004"},{"key":"B89","doi-asserted-by":"publisher","DOI":"10.1162\/003355304772839588"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.1287\/mnsc.2021.4126"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1509\/jmkg.73.2.88"},{"key":"B12","doi-asserted-by":"publisher","DOI":"10.1111\/poms.13619"},{"key":"B13","doi-asserted-by":"publisher","DOI":"10.1287\/orsc.1110.0678"},{"key":"B90","doi-asserted-by":"crossref","unstructured":"Boudreau KJ (2018) Amateurs crowds & professional entrepreneurs as platform complementors.
