The Product Life Cycle (PLC) is a model that explains the stages a product passes through during its lifetime in the market—from its initial launch to eventual decline.
- Each stage is associated with different sales patterns, customer behavior, competition, and marketing strategies.

1.) Introduction Stage:
- This is the stage when a new product is first introduced to the market.

- Profits are usually negative or low
Strategies:
- Create awareness and interest through intensive promotion
- Focus on early adopters
- Offer introductory pricing or samples
- Invest in advertising and product education
2.) Growth Stage:
