Apparently, Digital River has bought eSellerate, their largest competitor in the shareware e-commerce space.
I cannot find a press release about this. Digital River is a public company and if they are making an aquisition of this magnitude there should be a press release.
This is going to cause lots of shareware companies to once again try to find another ecommerce provider to get away from Digital River.
I'm not concerned about Digital River developing a monopoly because I don't think it can happen. The barrier to entry in the business is just too low and there are so many other options. You can always choose to set up your own system and not use an ecommerce provider at all (that is probably Digital River's biggest competition). PayPal and some other more general payment systems are always available as well. Plus new shareware ecommerce providers are starting up all the time - it's just too profitable a business for people to ignore.
