Wall Street moved lower amid a slump in media stocks including Viacom on disappointing earnings and concern about their profit outlook.
Shares of Viacom sank, last 12 percent lower, after the company posted lower-than-expected quarterly sales.
Shares of Walt Disney fell, extending Wednesday's 11 percent slide after the company downgraded the profit outlook for its cable networks unit.
Other media stocks including Twenty-First Century Fox and CBS also fell. Fox last traded 6.8 percent lower, while CBS was 1.3 percent weaker.
"As of now, after Disney all the media stocks are down and it seems people just want to get out of the sector at any cost and take any loss," CLSA analyst Vasily Karasyov told Reuters. "The selling pressure is relentless."
In late trading in New York, the Dow Jones Industrial Average slid 0.74 percent, the Standard & Poor's 500 Index fell 0.77 percent, while the Nasdaq Composite Index dropped 1.61 percent.
