This has, unsurprisingly, been reported in every media outlet imaginable.
In case you missed it.
Mariah Carey is virtually synonymous with Christmas — her holiday hit, “All I Want For Christmas,” has been a seasonal staple since 1994 and a reliable chart-topper in recent years.
Carey sought to make her reign official last year by filing a petition to trademark the title “Queen of Christmas,” meaning that no one else would be able to use it.
Her company, Lotion LLC, wanted to use that branding — as well as the terms “Princess Christmas” and “QOC” — for a range of products, from fragrances and makeup to clothing, jewelry and dog accessories, according to trademark applications.
That effort proved controversial, as at least two other artists known for their seasonal songs publicly took issue with Carey laying claim to the throne: Darlene Love, who said David Letterman christened her Queen of Christmas nearly three decades ago, and Elizabeth Chan, who describes herself as “music’s only full-time Christmas singer-songwriter.”
Chan officially filed a motion in opposition to Carey’s request earlier this year, on the basis that she herself had repeatedly been dubbed the “Queen of Christmas” and already used the brand “Princess of Christmas” in connection with her young daughter.
