The latest thing? Fashionable aim of an eccentric (9)

I believe the answer is:

infomania

'the latest thing?' is the definition.
(mania for the latest news)

'fashionable aim of an eccentric' is the wordplay.
'fashionable' becomes 'in' (similar in meaning).
'eccentric' is an anagram indicator.
'aim'+'of'+'an'='aimofan'
'aimofan' is an anagram of 'fomania'.
'in'+'fomania'='INFOMANIA'
