People always think you have to have over the 50% to control, but it's all down to whether you can be outvoted or not. In the case of Murdoch, its not. He can't be outvoted because no one entity can get enough shares to outvote him, thus he has control.

The situation with John Malone is similar, actually its more complicated! Most people don't realise that John Malone controls Discovery. He used to own the largest share holding, which was something like 40%, but now he is the second largest shareholder. But they have different classes of shares over there and the shares he holds gives him more votes, which gives him de facto control of the company.

I haven't checked for the new Sky company, but its either the same set up as BskyB, or Murdoch owns a different class of shares like Malone which gives him more voting rights and control. Whatever it it is, he controls Sky.
