SAG Awards committee chair JoBeth Williams explained that foregoing mail-in ballots and switching to an online-only system demonstrates the organization's commitment to environmentally sound practices. The 2009, 2010 and 2011 awards were honored with the Environmental Media Association's Green Seal, recognizing outstanding efforts for sustainable initiatives.
At the moment, only the nominee submissions have moved away from the paper ballot. The nomination ballots will be mailed November 21; the results will be announced on December 10. Final SAG voting instructions will be mailed December 31, with paper ballots available upon request for those who do not want to vote online.
The 19th Screen Actors Guild Awards ceremony will be telecast on January 27. The Academy is also deliberately moving toward electronic ballots for the Oscars. We'll see how soon they can put that into practice.
