In November 2011, Viacom announced it was moving from the New York Stock Exchange, after 40 years, to the NASDAQ Global Select Market. The opposite also occurs. In 2010, Charles Schwab, the large discount broker, moved from NASDAQ to the NYSE Euronext. Visibility plays a major role in such decisions today. When Groupon went public in late 2011, it selected NASDAQ because of a promise to promote its visibility and what it offers.
