Since the iTunes store launch in April 2003, users of the store have been requesting a longer preview windows for songs. Earlier this year, Apple finally started offering iTunes previews that were 90-second long (up from the previous 30-seconds) for US customers. Now, it seems that Apple has quietly expanded its 90-seconds iTunes previews outside of the US to other countries.
According to numerous reports, the 90-second previews have been expanded to Australia, New Zealand, Canada, UK, and some parts of Europe. The extended previews includes local labels as well as the ones that already had rights in the US. However, not all songs will have 90 second previews at this time.
In the US, Apple made the change by emailing music labels telling them that they would automatically extend the previews to 90 seconds. The decision to expand 90-second preview to international users may have been made by Apple and not directly by negotiating with music labels. Both the labels and publishers may have had objected to the terms but might not have had a legal stance. The reason for the delay in expansion to international markets is unknown.
