Q: Why Chanel 'No.5'?

A: Coco Chanel chose the fifth fragrance that perfumier Ernest Beaux produced for her. The official launch date was 5/5/1921.

A: Britvic, which distributes 7UP in the UK and Ireland, claims the brand was named after the seven main ingredients in the drink. The drink was originally created in 1929 after CL Grigg won a competition in the US to find the tastiest lemon and lime drink. But his original name for it -- Bib-label Lithiated Lemon Lime Soda -- was a little hard to pronounce.
