In other words, marketing exists within the dynamic context of our social trends and cultural forces, and whatever is happening at the moment, domestic and global.
Market research is that branch of marketing concerned with finding out why and how.
All of these are the territory of the market researcher. You will work closely with people from these and other departments to manage your new product's development, the test marketing, refining, formal introduction, and roll-out. These samegroups will also be necessary to keep your existing product on the market, updating it as necessary to meet changing demand and ultimately retiring it when the market for it declines. At the same time, the new product manager is introducing a replacement for the retired product. Professors like to teach it, students like to study it, and everybody thinks they can do it better than it is done now.
