It was a surprise to me—but apparently, the podcast audience in the US is not only rising, its’ exploding… A recent study by eMarketer shows that it was 18.5 million in 2007 and projects that it will rise to 65 million in 2012! Aiming to surf that wave, a San-Francisco-based startup called PodShow has developed an entertainment site focused on bringing video and audio podcasts to consumers. Podshow’s shows are short-form: they range from 2-7 minutes in length and several of the best performing shows are in HD. The site hosts several channels and podcasts about Business, Comedy, Fashion, Politics and Music. So far, PodShow has produced about 2,000 shows. You should go to the site and take a look - some are pretty irreverent and hilarious. The site also enables users to create their own podcasts to be distributed through the rest of the site. These podcasts are delivered as free downloads to users via the Internet, to any device (cell phone, MP3 etc). Interestingly, Podshow has received venture funding from big names: Kleiner Perkins Caufield&Byers, Sequoia and DAG Ventures.
