Declining corporate longevity may be an interesting topic to examine from the perspective of business history. In the United States, for example, the average age of the large companies listed on the Standard and Poor's 500 (or S&P 500) is currently 18 years, down from 90 years in the 1930s, 60 years in the 1950s, and 25 years in the 1980s. Some have forecast that the corporate longevity of S&P 500 companies will be just 12 years by 2027 and that 50.0% of the S&P 500 will be replaced by others over the next 10 years if the churn rate holds. A shorter median tenure of just five years for chief executive officers in the world's 2,500 largest public companies has also become the norm, one year less than it was in 2013, because of board impatience. At the other end of the scale, statistics reveal that 51.2% of small businesses in the United States are 10 years old or less, 32.5% of small businesses are 5 years old or less, 31.4% of new small businesses exit within their first two years, and that 48.9% of new small businesses close within their first five years.
