### Instruction:
Describe ZMOT (Zero moment of truth) and how it differs from the 3-step model of marketing that was prevalent at the time of its introduction.

### Response:
The 3-step model (ZMOT, FMOT, SMOT) of marketing from P&G begins with the consumer discovering a product via an Ad or hearing it from other sources like friends or colleagues. This trigger moment is followed by (FMOT) the first moment of truth where consumers are at the shelf, looking to buy, touch and feel the product and evaluate competitive offerings on the adjacent frames. The last step is the (SMOT) second moment of truth, where consumers purchase and start using the products.  

ZMOT (Zero moment of truth) is the time between the trigger and FMOT. It is when the consumers learn more about the products before they appear on the shelf. ZMOT is the pre-shopping experience where consumers can watch YouTube videos of the product, read Amazon reviews, and have a complete product experience before buying.
