The board's private sector and business team worked with a wide variety of large and small companies.

In 2006, winners included FBA, Glass Hammer, Synergy Creative Design & Marketing, Hoffi, 6721, Elfen, Zodshop and Departures.

This decision evoked a mixed reaction throughout Wales: welcomed by Cymdeithas yr Iaith Gymraeg but met with scepticism by others.
