The first decade of the 21st century challenged firms to prosper financially and even survive in the face of an unforgiving economic environment. Marketing is playing a key role in addressing those challenges. Finance, operations, accounting, and other business functions won’t really matter without sufficient demand for products and services so the firm can make a profit. In other words, there must be a top line for there to be a bottom line. Thus financial success often depends on marketing ability. - Philip Kotler and Kevin Keller, Marketing Management, 14th ed.
