 note = {Based on the product life-cycle theory of marketing, I propose a life-cycle theory of media-content creation—the content development three-year cycle theory. As per the work-experience of the author, the content creation cycle is hypothesized to be completed in minimum nine years. This period comprises three stages, each three-years long—Introduction Stage, Growth Stage, and Maturity Stage. This theory is examined through the achievements of seven creators, that is, pioneers who created media content; the mentors who influenced and instructed the author; and the author's contemporary creators who share and widen the author’s perspectives and make for healthy competitors.},
