JSON serialization

Hi, ALL,
I'd like someone to help me understand this situation.
Looking at the page: https://docs.djangoproject.com/en/dev/topics/serialization/ the part which says "Serialization formats->JSON" there is an example of how the data would be serialized.
The sample uses the symbol "double quotation".
 
On my machine I have django 1.6.1:
 
C:\Documents and Settings\Igor.FORDANWORK>python
Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information. 
>>> import django
>>> django.get_version()
'1.6.1'
>>>
 
In my views.py I'm using following code:
 
usb_list = serializers.serialize("json", USB.objects.all())
return render_to_response('html/index.html', {"usb_data": usb_list} )
 
where USB is the data model class.
This class overrides a __unicode__() function to produce a good output on the console.
 
Now when I go to the page to see it in the browser I see the data as a JSON but the data is surrounded with a text """.
 
So in the docs I see something like this: "abc", while my application will show: "abc"
 
In the index.html I have this code:
 
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
{% load staticfiles %}
<script type="text/javascript">
    var data = "{{usb_data}}";
# some more JavaScript code
</script>
<html>
</html>
 
Is this a recent change? Am I doing something wrong?
Thank you.
