“Mariah’s World” originally aired on E!, the American cable network known for entertainment news and celebrity-focused programming. The reality docuseries premiered on E! on December 4, 2016.
The eight-episode series followed Mariah Carey as she prepared for and performed on the Sweet Sweet Fantasy Tour while also planning her wedding. Carey resisted labeling it a conventional reality show, saying she wanted viewers to see more of her personality rather than simply watch a manufactured celebrity lifestyle.
The show was announced in March 2016 and was produced by Bunim/Murray Productions and Magic Carpet Productions. Carey served as an executive producer alongside Stella Bulochnikov, making the series both a behind-the-scenes tour record and a closely managed portrait of the singer’s professional life.
International broadcasts also appeared on local E! channels, including outlets in Australia, New Zealand, the United Kingdom, Ireland, and France. MTV, VH1, and Bravo are plausible distractors because they have also carried celebrity and reality programming, but they were not the original network for this series.
