NBC Universal, the US media conglomerate, is reported to be in discussion to acquire DreamWorks SKG, a film company co-founded by Steven Spielberg, which could be worth around $1bn (€833m) and was kept separate from the Dreamworks flotation last year.

This morning's New York Post reported that three sources familiar with the matter confirmed that the publicly-listed DreamWorks has been offering its private film unit for sale.
