Galway Bay fm newsroom - Profits at Smyths Toys - which is headquartered in Galway City - surged by over €35m last year.
The combined sales of the group's businesses in Ireland, the UK and Europe amounted to €1.2bn.
Smyths Toys was founded in 1986 by brothers Tony, Padraig, Liam and Thomas Smyth in a grocery shop in Claremorris in Co. Mayo.

It generated revenue of €1.2bn last year - with profits significantly rising by some €35m.
