A study from American Life Project shows that podcasts are still unpopular and that few people listen to them. Out of 1,000 people surveyed, only 10 regularly use podcasts:
The numbers would lead one to believe that the poor adoption results are due to a lack of new individuals trying the relatively new technology, but according to the same study, the number of people who have ever tried Podcasts has gone up 5 percent in less than a year—from 7 to 12 percent. So why aren't people listening to podcasts? We have several theories on the matter, all of which make broad, sweeping generalizations.
People don't find random people rambling into a microphone about their lives all that interesting. It seems that most people that have interesting enough lives to warrant interest from the general public are to busy actually living their own lives to podcast, or they have little-to-no clue as to what a podcast is. Throw in the terrible quality of the majority of podcasts and you have a combination for a very small audience.
