The Hollywood Reporter was the first to report this spring that Greenstein would be part of the management team installed by Ellison at the newly configured conglomerate. Its not clear exactly what his job will be, but its expected to extend beyond only Paramount Pictures.

The FCC approved the deal on July 24, but it wont officially close until August 7 or thereabouts. Its not clear whether Ellison will wait until then to officially announce his roster of executives beyond whats already known.
