Helium

Helium.com, Inc. was founded in 2006 as a Yahoo! Answers-style website created from user generated content paid on a revenue sharing model. Over time the site evolved from short answers to stand-alone articles, and began to offer writers the opportunity to earn from selling articles as well as passive income. The sale of articles to businesses and publishers is now its primary business, and the revenue share arm has closed to new members, effective May 21, 2014. The sites which display revenue share articles will be closed down on December 15, 2014.http://en.wikipedia.org/w/index.php?title=Helium.com&oldid=609032188

Important News from Helium Publishing
May 14, 2014, 01:56:50 PM
After eight years and well over one million articles, we regret to announce that Helium Publishing will be closing. By 12/15/14, the Helium Publishing 360 sites will no longer be live. It's been a good run -- and that is due in no small part to your dedication and hard work. 
DETAILS: The Helium Publishing 360 sites will be available on a read-only basis effective May 21, 2014 and will continue to be available on a read-only basis until December 15, 2014. During this period, if you have an existing Account, you will continue to have access to your Account and accrue potential Minimum Amount Threshold, but you will not be able to add more articles to the Helium Publishing 360 sites or create a new Account. If you have attained the Minimum Payout Threshold, which currently is set at $25.00, we strongly encourage you to withdraw your Minimum Amount Threshold because the Helium Publishing 360 sites will terminate on December 15, 2014 and you will no longer have access to your Account. 
Why are the Helium Publishing 360 sites shutting down? Changing market conditions and the proliferation of competitive publishing outlets and free blogging tools, as well as declining usage and revenue, were all contributing factors. After careful consideration it was determined that the existing business model cannot be sustained. http://forum.heliumnetwork.com/index.php/topic,2638.0.html
