Wow, is that ever confusing!
"Majority" of shares, but not
"super voting" shares, giving them (CBS) a
"minority" on the board, while someone else (Field & family)
"controls" the company ("new" Entercom).
A common strategy when a closely held private company goes public is to create two classes of shares. Often the shares sold "on the market" will be one share = one vote, but the shares held by the original founders or owners will be many votes to each share. So if the super-shares each had 10 votes, you could have a total of 10,000,000 shares... one million super shares and 9 million regular ones, and the supershare holders would still control the company.
