So, Daniel Loeb is an activist, libertarian investor who helped run off Yahoo's old CEO, went halfsies to buy Deadline's sibling site Variety, and signed on to the Supreme Court amicus brief supporting gay marriage. Now Loeb has sent an unusually pleasant (at least for him in these often confrontational situations) letter to the president of Sony, suggesting that they work together to spin off the company's entertainment assets. What's that about, Deadline's David Lieberman asks, in laying out some background on Loeb and his most interesting proposal here: http://www.deadline.com/2013/05/who-is-daniel-loeb-and-what-does-he-want-with-sony/ This is definitely one to keep watch on. It could affect Sony's massive investments in film production and distribution, TV production, home entertainment and music. What do you think about the proposal?
