Funny tales etc. featured in what's seen on the box (8)
I believe the answer is:
telecast
'what's seen on the box' is the definition.
('the box' can refer to a television)
'funny tales etc' is the wordplay.
'funny' indicates anagramming the letters.
'tales'+'etc'='talesetc'
'talesetc' anagrammed gives 'TELECAST'.
'featured in' is the link.
(Other definitions for telecast that I've seen before include "TV broadcast" , "TV programme?" , "TV transmission" , "TV show" .)
