Distribution Channels: The concept of Product Life Cycle (PLC) provides valuable guidance to marketing managers in optimizing distribution channels. During the introduction stage, they may opt for selective distribution to create awareness and control initial costs.

As the product transitions into the growth stage, it can strategically expand distribution to reach a broader audience and capture market share. In the maturity stage, adjusting distribution to target specific market segments or regions becomes essential to maintain product relevance.

PLC empowers marketing managers to adapt distribution strategies as the product evolves through its life cycle, ensuring efficient market penetration.
