# What is the correct JSON content type?

I"ve been messing around with JSON for some time, just pushing it out as text and it hasn"t hurt anybody (that I know of), but I"d like to start doing things properly.

I have seen so many purported "standards" for the JSON content type:

application/json

application/x-javascript

text/javascript

text/x-javascript

text/x-json

But which is correct, or best? I gather that there are security and browser support issues varying between them.

I know there"s a similar question, What MIME type if JSON is being returned by a REST API?, but I"d like a slightly more targeted answer.

For JSON text:

The MIME media type for JSON text is application/json. The default encoding is UTF-8. (Source: RFC 4627)

For JSONP with callback:

application/javascript
