With Comcast now vying for segments of Twenty-First Century Fox, investors are scrambling to figure out what the move could mean for the media giants.

Though one of the largest media companies worldwide by market value, Comcast has just a small presence abroad. But a move to acquire components of Fox's extensive international assets could flip the script.

The discussed deal would more than double annual international revenues for Comcast.

Fox's international assets would comprise about 70 percent of the value of the businesses for sale in the proposed Comcast all stock deal, according to CNBC's David Faber. The NBCUniversal parent is also eyeing Fox's movie studio, cable networks and its regional sports network.

Comcast shares closed lower by 2.5 percent Friday in wake of the news of the possible deal. Fox shares were 6.2 percent higher.

Disclosure: Comcast is the owner of NBCUniversal, the parent company of CNBC and CNBC.com.
