Most successfull JSON alternative which supports binary data

There far too many JSON alternatives which support binary data:

• http://de.wikipedia.org/wiki/Protocol_Buffers (Schema is required)
• https://en.wikipedia.org/wiki/MessagePack (Schema is optional)
• https://en.wikipedia.org/wiki/CBOR
• http://bjson.org/
• https://github.com/FasterXML/smile-format-specification
• https://en.wikipedia.org/wiki/BSON

AFAIK there is not sane default up to now.

I know that I can encode/decode data in base64 by hand. But I would like to avoid this. I want a data format, not a work-around.

I guess in ten years we will know who has won the race.

Which JSON alternative which supports binary data the most wide spread today?

Please provide a link to your source of information. If you guess, then please state this.
