A Lehman Brothers analyst downgraded the entertainment industry Monday and slashed forecasts for its five major companies, saying digital downloads of movies and TV shows posed a huge threat to profits from DVD sales that the companies rely on. The stocks of The Walt Disney Co., News Corp., CBS, Time Warner and Viacom fell slightly more than the broader market by the close, with CBS falling the most, by 4.7 percent, or 87 cents, to $17.73.
