How to change ASP.NET WebMethod's 'd' identifier in a JSON response, to a different name?

Question

This works: through jQuery I'm using a jQuery.ajax(..) call to a page e.g. Default.aspx/GetStatus having a WebMethod attribute:

// Default.aspx
[WebMethod()]
static public bool GetStatus(long id)
{ //...

The JSON response contains the correct boolean value in the format { d: true }. However I don't understand the origin of the resulting "d" member name.
Where does the "d" identifier come from (how is it decided) and how can I change its name?

What does .d in JSON mean?

+1 That's awesome - I laughed at "well it had to be something". So that answers half the question, which I can live with. Do you have any idea how to change it? – Counterfactual

Well, if you want to change it real bad, you could modify the rendered response with an HttpModule, as indicated here: devx.com/vb2themax/Article/19901/0/page/3 – Infinitive

Or you could wrap all your calls to the service with a JavaScript function that creates a new property. Neither of which sounds like a great idea. – Infinitive
