Despite the fall of public companies, the number of mutual funds available in the market has exploded in the past few decades and remains high. At the end of 2017, nearly 8,000 mutual funds existed in the US market as shown in the chart below. To put this number in perspective, there were only 361 funds in 1970. Then the number jumped to 564 in 1980. Since then the number of funds have steadily increased year over year until the dot-com crash of early 2000 and the global financial crisis of 2008-09.
