consider the three major categories of the new product:

1."really new" products (ones that create new products like iTunes for digital music),

2.new products in existing product categories, and

3.line extensions which are just new varieties of existing products (such as new flavors).

How does a job of the marketing manager forecast product demand each of these categories?

*please note that this is BUS 5112 Marketing management discussion assignment. It is about new product development and product life cycle.
