Additional History on the Pink Sheets / The National Quotation Bureau Prior to the Pink Sheets in the early 1900’s, over the counter markets were completely fragmented. Up until 1999 the OTC stock prices (the buy and sell prices) were printed on pink colored sheets of paper and sent to stock brokerage firms and investment houses. That is why the investment community used the term Pink Sheets.
Before the Pink Sheets circa 1900 stock brokers and investment bankers would offer to buy and sell stocks by advertising in daily newspapers. They would also print out material about the stocks they were offerings to sell and the kinds they would be willing to buy. The investment banks then sent this information to clients and other investment banks.
The Pink Sheets were set up to take over this function of getting the buy and sell prices from all the investment banks. They would collect each day the prices that stockbrokers were willing to buy or sell stock for then would deliver them each morning to all the stock brokerage firms and investors. This served a similar function to what Nasdaq would one day do. Nasdaq is just the automated quotation of stock prices. The buy and sell prices of what stock brokerage firms are willing to buy or sell stock for. Nasdaq is a real-time dealer quote service.
The Pink Sheets continued to deliver pink colored sheets of paper until 1999 while Nasdaq and the OTCBB had been doing in for years. But in 1999 they became electronic and have been becoming more and more popular. They were out of favor prior to 1999 because you had to call a stock broker to get quotes but they have come roaring back to compete with the OTCBB and the Nasdaq. The Pink Sheets predates the Nasdaq and the OTCBB and have been around now for over a century.
