Why not all businesses trial new their new products?

Reason for this can be because:

• It is seen as a waste of time for the firm
• It is too expensive to do
• Their may already be high demand for the product due to the brand name and so product trialing is not needed
• Afraid of competitors finding out about their product and do not want to reveal it on trial as the product may be copied.
• Multinationals use countries as test markets instead.
