When companies and shareholders look back at 2008, they’ll remember a year when debt and a horrendous advertising climate decimated companies, turning multi-billion dollar businesses into penny stocks. Shares of Sirius XM (SIRI) plummeted post-merger, ending 2008 at just 12 cents, down 96% for the year. Westwood One (WON) lost 98% of its value and was delisted from the New York Stock Exchange. Citadel (CDL), Salem Communications (SALM) and Entercom (ETM) all fell 90% or more from their highs of 2008. Radio One (ROIA) and Emmis Communications (EMMS) each ended the year with stock values below 45 cents a share, while Spanish Broadcasting (SBSA) & Regent Communications (RGCI) were below 10 cents a share. CBS, Cumulus Media (CMLS), Journal Communications (JRN), Fisher Communications (FSCI) and Arbitron (ARB) all reached historic lows.
