Bigstockphoto was founded in 2004, they reportedly had rapid growth initially and then tapered off as more and more agencies opened for business. In September 2009 Shutterstock bought Bigstockphoto and changed their name to Bisgstock. Shutterstock primarily sells subscription packages to buyes looking for a lot of images and Bigstock is a more traditional microstock enterprise for them to acquire. The Bigstock website has recently had a much needed revamp and now  not only looks a lot more modern, but also operates very smoothly.

I have not been contributing to Bigstock for very long and cannot accurately judge the site performance yet. Other photographers have reported Bigstock as within their top 5 agencies. Sales income is said to be lower than of  Fotolia and Dreamstime, but more stable. I find their review and submission process one of the easier ones to go through and very few rejections. They do only have a portfolio of just over 4 000 000 and perhaps they are trying to build up to a Shutterstock level.  Other microstock contributors rate Bigstock as a worthwhile agency to submit to, I would say send a portion of your portfolio and then monitor sales to see whether they are worth it for you.
