A new study by the British Market Research Association finds that 25% of internet users will listen to a podcast in the next six months.  The study, completed in the UK, found that 17% of internet users have already downloaded a podcast in the last six months, and that number is expected to grow to nearly a quarter of all internet users in the next six months.  Currently, according to the survey, over 10.8 million Brits own portable MP3 players, and that number is expected to grow by over 40% (or 4.3 million units) in the next six months.
