'organising topics and streaming at last' is the definition.
I can't tell whether this definition defines the answer.

'organising topics and streaming at last' is the wordplay.
'organising' indicates anagramming the letters.
'at last' says to take the final letters.
The last letter of 'streaming' is 'g'.
'topics'+'and'='topicsand'
'topicsand' with letters rearranged gives 'podcastin'.
'podcastin'+'g'='PODCASTING'
