Step 1 : Introduction to the question "Which soft drink brand became the first to be sold in an aluminum can?"
RC Cola (Royal Crown Cola) made history in 1960 when it became the first soft drink to be commercially sold in an aluminum can. This innovation marked a significant shift in beverage packaging, as aluminum cans were lighter, more resistant to breakage, and easier to transport than traditional glass bottles. The move helped pave the way for widespread adoption of canned beverages across the soft drink industry, eventually becoming the dominant packaging format worldwide, especially in supermarkets, vending machines, and large-scale distribution networks.
