Newsgroups suitable for all developing teens (6)

I believe the answer is:

usenet

I'm a little stuck... Click here to teach me more about this clue!

'newsgroups' is the definition.
I know nothing about this answer so I can't tell whether this works.

'suitable for all developing teens' is the wordplay.
'suitable for all' becomes 'u' (universal dvd certificate).
'developing' is an anagram indicator.
'teens' anagrammed gives 'senet'.
'u'+'senet'='USENET'

Can you help me to learn more?

(Other definitions for usenet that I've seen before include "Internet facility" , "Newsgroups worldwide" , "news system" .)

I've seen this clue in The Hindu.
