Their website: www.bigworldnetwork.com
I first found out about this when I went to Minicon last month; they had a table in the dealers' room, and I took a look despite not doing much in the way of writing lately. When I discovered yesterday that I still had the postcard I picked up from their table, I took a look at the site.
They run web serials, mostly fiction, in set blocks. In fact, they refer to them as 'seasons' and have a setup somewhat reminiscent of television programming. There aren't any specific terms about payment on their website (ETA: compensation is mentioned, but not described in detail), and when I asked at Minicon, they didn't have a contract handy. (From what they said, I'm guessing this will be rectified at any future convention appearances they make.) I took a look at some first chapters up on their site and I'm not very impressed with their quality so far. They've just started out in the past year or so, so I don't know if that's a factor or not.
Anyway, there doesn't seem to be very much information on them. Anyone else have anything to contribute?
