What, if anything, does it have to do with the factory pattern?
Or if nothing, then why is it called a factory? It seems more like a singleton to me.

Both `.service` and `.factory` create a singleton. Here's more info: http://stackoverflow.com/questions/14324451/angular-service-vs-angular-factory – New Dev Jan 10 '15 at 08:22

@richard, because it creates an instance within the `.factory` function and returns it. `.service` on the other hand news up a service. – New Dev Jan 10 '15 at 08:34

@New Dev but what does that mean it "news up a service"? It's not a singleton then right? You got a new instance? – richard Jan 10 '15 at 08:36

No, you'll still get a singleton. – New Dev Jan 10 '15 at 08:38

So then I don't know what it means when you say it news up an instance. It's not new...:-( – richard Jan 10 '15 at 08:38

@richard, read again the link I gave you and you'll understand what I mean by "news up". – New Dev Jan 10 '15 at 08:54

Because it is a factory, as in factory pattern. – a better oliver Jan 10 '15 at 14:40

My guess is that a factory can be used to create factory functions
app.factory('MyFactory', function() {
// The returned function is available by injecting MyFactory
// into other components
return function() {
return 'Something created by the factory';
};
});
This can be used, for example, in a controller
app.controller('MyController', function(MyFactory) {
var myObj = MyFactory();
// myObj is 'Something created by the factory'
});
(You can do something like this using service as well. I think you just have to live with the fact there is almost complete overlap between what you can do with factory and service)

Thanks Michael. I think it's an unfortunate choice of words for them to name it a factory. – richard Jan 11 '15 at 17:36
