Facebook amended its S-1 registration with the SEC late Wednesday to include exhibits detailing its relationship with Zynga, but maintained the $5 billion proposed value of its IPO. The exhibits included a developer agreement between Facebook and Zynga, which makes the popular Farmville game for the social networking site. The agreement includes quarterly targets for increasing monthly unique users, although Facebook [S: FB] sought confidentiality protection for the specific numbers. In the developer agreement included in the revised filing, Facebook acknowledges it "desires to enable Zynga to build the Zynga Platform on top of the Facebook Platform." In 2011, Zynga accounted for approximately 12% of Facebook's revenue. Facebook filed plans for its widely anticipated IPO last week. Shares of Zynga fell 1% after hours.

CHICAGO (MarketWatch) -- News Corp. Chief Operating Officer Chase Carey said Wednesday that "TV Everywhere," the effort by content providers and cable operators to tie online video viewing to pay-TV subscriptions, is still a good idea, but the industry is taking too long to implement the strategy. "I think in this world, you can't spend three or four years getting something going," he said during a conference call with analysts. "And I think the secondary concern is ... [that] I would rather see there be much more of an open architecture around authentication. We've got to execute it better." TV studios and networks, worried that many people will cancel their pay-TV subscriptions and simply stream the shows they like from the Internet, are working to set up a system that will verify that someone is cable, satellite or fiber video customer, and then let them watch a particular program. However, the system has been discussed since at least 2008, and has yet to be rolled out on a broad basis.
