So we were interested in this CNN story on the 20 biggest CEO pay raises. The winner? Viacom CEO Philippe Dauman. He got a raise of $50.5 million in 2010. That represents an impressive 149 percent pay increase from his 2009 compensation of $34 million.Iit makes us wonder about the merits of spending even more taxpayer dollars (and trampling civil liberties) to better protect Viacom copyrights. Making movies seems pretty profitable as it is. And it seems a bit counterintuitive for a company that says its business is threatened by piracy to be so lavish with executive compensation. Neither the MPAA nor Viacom were willing to comment on this story.
