Millions enthralled by older article represented as the best ever (3-4,6)

'the best ever' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'millions enthralled by older article represented' is the wordplay.
'millions' becomes 'm' (abbreviation).
'enthralled by' means one lot of letters goes inside another ('enthral' can mean 'capture').
'represented' indicates anagramming the letters.
'older'+'article'='olderarticle'
'olderarticle' is an anagram of 'alltierecord'.
'm' put within 'alltierecord' is 'ALL-TIME RECORD'.

'as' is the link.

Can you help me to learn more?
