(Reuters) - Veteran media executive Edgar Bronfman Jr. has sweetened his bid to take over Paramount Global, offering $6 billion for its controlling shareholder National Amusements and a minority stake in Paramount.

Bronfman's original offer was for $4.3 billion, according to Reuters sources.

The competing offer for the home of Paramount Pictures, the CBS broadcast network and cable networks such as MTV threatens to undo a planned acquisition by tech scion David Ellison and his firm Skydance Media.

Paramount and Skydance Media signed a merger deal in early July. The agreement included a 45-day "go-shop" period to consider other offers. A special board committee has extended Wednesday's deadline until Sept. 5 for Bronfman's consortium.
