We construct a high frequency dataset of firm mentions on the three major business news networks, CNBC, Fox Business and Bloomberg, studying the closed caption (CC) data that accompanies national TV broadcasts. Firm prices appreciate on the days firms are covered by TV. Mentioning a firm on TV is associated with significantly larger abnormal returns than references in print media and the DJNW. Using intraday data, we show the extensive-margin effects are concentrated in the 30-minute window around the TV mentions of the firm.
