Internet services firm Livedoor Co. and Fuji Television Network Inc. might reach a deal by the end of the month that would draw the curtain on their highly publicized battle over control of Nippon Broadcasting System Inc., sources said Wednesday.

Livedoor's takeover of the radio broadcaster was widely seen as an effort to exert influence over Fuji TV, whose largest shareholder at the time the takeover bid began was NBS. For the past few weeks, Livedoor and Fuji TV have been in negotiations on the possibility of forging an amicable alliance.

Sources said that one item in the proposed agreement calls for Livedoor to "effectively sell" most of the shares it has acquired in NBS, enabling Fuji TV to make the radio firm its subsidiary.
