Scottish firm Wolfson Microelectronics is another beneficiary of huge public demand for iPods and other electronics products.
The company supplies components for such devices from Apple, Microsoft and Sony. Consumer demand has tripled the company's revenues to £29 million, mainly on strength of iPod success.
Company founder and CEO David Milne told The Scotsman: "It is not just an iPod boom. The portable product has generally taken over. Apart from the wide range of MP3 players, I think multi-media phones will be the red rooster for the group this year."
The company's financial report cites Milne saying: "Wolfson is benefiting from the digital revolution and has delivered another year of strong growth in revenues and profits. Wolfson’s products are enabling more and more global consumer electronics companies to provide high quality audio and other features in their products."
Wolfson’s profits for 2004 came in at £8.8m, up 34 per cent on the previous year.
The company anticipates solid growth for the first half of 2005.
