Entertainment from crosswords? How bizarre! (7)

I believe the answer is:

showbiz

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

'entertainment' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'from crosswords? how bizarre' is the wordplay.
'from' indicates the answer is hidden within the clue.
'SHOWBIZ' is hidden within 'crosswords how bizarre'.

Can you help me to learn more?

(Other definitions for showbiz that I've seen before include "Theatre, TV, movies etc" , ""Bright lights" entertainment?" , "Stage and film entertainment" , "Entertaining" , "World of bright lights, the theatre etc" .)

I've seen this clue in The Telegraph.
