I've had an application running in Second Life for the last 5-6 years to facilitate people making machinima. I haven't changed the price since it launched, at around $6 USD. When it first launched (also when SL was much more popular), I was selling several hundred dollars a month.
I still pull in $30-$50 a month on it, but I don't do much to promote it anymore. Linden Lab has really fucked up over the years and the quality of their software (the environment my app runs in) has gotten considerably worse. Its sad to say that my machinima app ran better 5 years ago than it does today, and multiple re-writes over the years has proven it impossible to go any further with the it.
Alternatively, I just put my first app up in the App Store last night. Its waiting for approval. I'm going to keep launching small utility apps and see where it goes.
I also did a stint in SecondLife, trying to build web-enabled in-world products and/or build web services that would take Linden dollars for payment. Probably made $600 in revenue.
