"And the times, they are a' changin'!" In this presentation, we discuss the major stock market exchanges including the New York Stock Exchange, the American Stock Exchange (now called the NYSE MKT), and the NASDAQ, as well as the less reputable over-the-counter markets such as the Bulletin Board and the Pink Sheets (now called the OTC Markets). What we will see is that technology and the urge to consolidate are changing the industry at breakneck speed.
