Drat. Carl Icahn gives up his effort to break up Time Warner. I talked with some big-business guys who’ve worked atop and with big-media companies after Icahn’s report on TWX came out and they agreed it was “80 percent right.” But now the company will blob along with a few more minor changes, a few baby steps in a world that needs giant steps. Damn. My FU money keeps telling me to FU.
