$ prefix in angularJS
It is for angularJS predefined service only.
It is just a naming convention from the below snippet http://docs.angularjs.org/tutorial/step_05

‘$’ Prefix Naming Convention
You can create your own services, and in fact we will do exactly that in step 11. As a naming convention, angular’s built-in services, Scope methods and a few other angular APIs have a ‘$’ prefix in front of the name. Don’t use a ‘$’ prefix when naming your services and models, in order to avoid any possible naming collisions.
