Washington Post business columnist Jerry Knight points up the differences between the iconic, pun-cracking Louis Rukeyser, recently-deceased original host of Maryland Public Television’s Wall Street Week, and over-the-top stock modern stock pickers such as Jim Cramer. “Watching Jim Cramer on CNBC, ripping the head off a toy bear, then raking his audience with machine-gun sound effects, left me longing for the days when Louis Rukeyser was considered ‘too showbiz’ to be talking about stocks on television,” he writes.
