If you look at the Popular Items Tab in the Stock Footage. you will see the Top Authors and the Number of Sales they have Each Month. Example: Pressmaster - who is the Top Seller as far as I can remember,… he used to have 5000+ sales a month… now only about 3000 a month. Others in that list who used to have about 500-600 a month now have 400 or less… This is as a result of two things… 1). There are far more Authors uploading more Stock Footage to the site, and 2). the Stock footage Market has probably reached a peak for buyers. Basically, Envato is rapidly gaining More Stock Footage Items, but not increasing its Sales. So less Sales to go around for the increasing number of Authors.
