There are many brand names that are misspellings of real English words. Instead of calling them misspellings I would like a more positive term for this type of name.
Wikipedia calls it sensational spelling:
Sensational spelling is the deliberate spelling of a word in an incorrect or non-standard way for special effect.
Sensational spellings are common in advertising and product placement. In particular, brand names such as Cadbury's "Creme Egg" (standard English spelling: cream), Weetabix (wheat), Blu-ray (blue), Kellogg's "Froot Loops" (fruit) or Hasbro's Playskool (school) may use unexpected spellings to draw attention to or trademark an otherwise common word.
