There may be more and more podcast content available, but day-to-day podcast use remains static, research claims.

The Pew Internet and American Life Project found that 12 percent of US people who are online have downloaded a podcast - up from 7 percent in a survey taken in February 2006.

However, the survey results also point out that just 1 percent of those surveyed would download a podcast on a daily basis, unchanged since February.

With 207,161,706 estimated internet users in the US, that 1 percent figure still represents a lot of listeners.

Mary Madden, senior research specialist at the research company said: "We are at a crossroads of a major transition in the way media content is delivered and consumed."

Fifteen percent of online men say they have downloaded a podcast compared to just 8 percent of online women, the report reveals. In addition, those who have used the internet for six or more years are twice as likely as those who have been online three years or less to have downloaded a podcast (13 percent vs 6 percent).
