"The Little Mermaid" font

[Mr. Brass Bonanza]

Why has the font for The Little Mermaid keep changing. I understand why it's different for the Broadway show, but for the movie and sequels, it has changed several times. The original font appears in the movie itself, the original release of the soundtrack, and the original release of the VHS tape. Since then, it keeps changing. Does anyone know why? I don't see this happen with the properties of other movies, such as Beauty and the Beast and Aladdin.

Thanks!
