The majority of large companies do not sustain revenue streams or expand them over time, Columbia University professor Rita Gunther McGrath writes. According to her research, half of companies saw revenue drop by 10% or more during at least one year between 2000 and 2009. Other studies support this concept, including one that says the lifespan of companies in the Standard & Poor's 500 index has been steadily shrinking for decades.
