In a celebrity-obsessed society, how effective are A-listers at focusing public attention, support and advocacy on our causes? Kenneth Jost with CQ Press just released a fantastic whitepaper that explores the good, the bad and the ugly of celebrity advocacy.

He takes an amazing historical look at celebrity involvement in charities over the decades (Comedian Milton Berle hosted the first TV telethon for cancer research in 1949).

And he reports that right now more than 2,800 celebrities are publicly supporting around 1,800 causes.

With all that red carpet cachet, are non profits leveraging celeb potential for good or wasting resources in a big ole glitter bomb? Check out the report.
