Back in 2005 the New Oxford American Dictionary named "podcasting" its word of the year.
At that point it certainly looked like the downloadable audio and video programs would radically change the way we consume media, and would empower amateurs to become popular producers.
Podcasting is indeed changing the game, but perhaps not as quickly as the dictionary folks might have guessed.
New data from the Pew Internet and American Life Project finds just 19 percent of all Internet users have downloaded a podcast so they could listen or watch it later. That's up from 12 percent in August 2006, but very few Internet users actually download podcasts on a typical day, according to Pew's Mary Madden.
