Hey! So, I was wondering if you could summarize W. T. Tucker's (1964) and Jacob Jacoby and David B. Kyner (1973) definitions of brand loyalty? Each theorist summary should be about three hundred words and please don't copy and paste. Also, why would Jacoby and Kyner's be the better definition to understand brand loyalty?
