Which individual secured the rights to market the Milky Way recipe outside of the United States following a family falling out?
Answer
Forrest Mars, the son of Frank C. Mars.
The international divergence in Milky Way branding is directly attributed to a significant falling out between Frank C. Mars and his ambitious son, Forrest Mars. Following this disagreement, Forrest Mars left the family business and relocated to England. As part of the separation, Forrest secured the rights to utilize the Milky Way recipe outside of the United States market. This pivotal decision led Forrest to create variations tailored to different regional palates, most notably introducing the sweeter international Mars bar, which uses the recipe familiar to Americans as the standard Milky Way.
