The companies have reopened talks to form a joint venture that would feature video content from all four networks, according to a report in The Wall Street Journal.
The venture is reportedly an effort by the four media giants to gain online advertising revenue from internet postings of TV shows, something that media groups have been accusing YouTube of doing since its launch.
With more than 100 million videos served daily, YouTube is the top video sharing site on the internet.
The company has a policy of removing any copyrighted materials at the request of the owner. But clips, and in some cases entire episodes, of dozens of popular TV shows are uploaded by users daily and can easily be found on the site.
