What Big M's Advertising History Teaches Us About Brand Rejuvenation

Few Australian brands carry as much nostalgic weight as Big M. Its advertising throughout the 1970s and 80s became part of the cultural furniture, memorable and instantly recognisable to a generation of shoppers. Decades on, people still search for those old campaigns, which says something important about brand equity: memorable creative doesn't just sell a product in the moment, it builds an asset that keeps generating awareness long after the media spend has stopped.

For brand owners today, the Big M story is a useful case study in what we call brand rejuvenation: reconnecting a heritage brand with a new generation of customers without abandoning the equity that made it famous in the first place. The brands that get this right don't chase nostalgia for its own sake, they identify the emotional truth that made the original work and translate it into a modern context.

At The Sphere Agency, this is core to how we approach brand repositioning and revitalisation projects: understand what people already love about a brand, protect that asset, and rebuild the parts that have stopped working. If your brand has history but its current advertising isn't landing the way it used to, that's usually a sign it's time for a rejuvenation conversation, not a full rebuild.
