"Known for its soft serve ice cream, Dairy Queen has been serving its Blizzard treat — soft serve with mix-ins — since 1946, with the name first trademarked in 1952; after W.B. Mason began selling products called Blizzard, Dairy Queen filed a complaint seeking an injunction and profits, arguing there is a likelihood of confusion (and claiming W.B. Mason’s use threatens irreparable injury) because Dairy Queen also sells water." - Rachel Leah Blumenthal
