They still appear split — even though, as a practical matter, they have to reach an agreement by midnight in order to have something ready for the official Wednesday deadline. That drove most company shares down, with a late uptick possibly softening the blow. The Dow’s U.S. Media Index was down 1.2% about 20 minutes before the end of the trading day. Disney was hardest hit among the industry’s biggest players: Its shares were -3.5%, followed by Sony (-3.4%), CBS (-2.3%), Viacom(-2%), and Time Warner (-1%). Comcast was up about 0.5%. Among other media companies, Cinedigm (-8.8%) and RealD (-7.2%) took the worst beatings. Others down at least 4% include E.W. Scripps, Entercom, Crown Media, Netflix, National CineMedia, Live Nation, LIN TV, and Dish Network. Gainers include Westwood One, Barnes & Noble, Sirius XM, Radio One, McClatchy, and McGraw Hill.
