The survey found that 75 percent of British users do not listen to less live radio as a result of listening again online, with 50 percent tuning into new shows as a result.

The situation is quite similar as for podcasting, with one-fifth saying they now listen to more live radio and nearly one-third saying they listen to new radio shows after sampling them via podcasts, MediaGuardian reported.

Only eight percent of respondents said they tune into less radio because of the availability of podcasts. Of the 4.3 million who have downloaded podcasts, about 1.9 million listen to at least one podcast each week.

Two-thirds of podcast listeners subscribe to their shows through iTunes, with about half tuning in during the evening. Of these, 80 percent listen through their computers and 61 percent through their MP3 players, according to the survey.

The most popular genres are music and comedy - each user subscribing to more than three podcasts on average, and listening to 53 minutes each week.

The survey also indicates that a free, advertising-supported format would be accepted by most listeners – 58 percent expresses interest, but less than one-third said they would subscribe to a paid-for service without advertisements, MediaGuardian reported.
