Though initially the appeal of the podcast was for those who wished to make their own radio-type shows available to the general public, the use of pod and vodcasting has grown in leaps and bounds. Among the various ways pod and vodcasting have been and continue to be used are--
• Supplements to news organizations and newspapers
• A way around the traditional broadcasting rules for various organizations
• Educational use for lectures and homework
• Political uses
• Religious uses including sermons and talks
• Audio and visual tours of museums, cities, and other cultural points of interest
• Space communication
• Commentaries on television shows
• Sports broadcasts
• Conference and meeting updates and feedback
• Digests for academic journals
• Public libraries
• Law enforcement
• Alternative for live music audio streams and DVD commentaries
• Computer teaching tool (screencasting)
USA Today came up with a "top ten" list in February 2005 and of those ten, four of the presentations were on technology, three were about music, one was on the movies, one centered on politics, and one was a "couplecast" called The Dawn and Drew Show. Soon after this, several podcasting networks began appearing including the GodCast Network, the Tech Podcasts Network, and the Association of Music Podcasters. The first internet podcast community, Podcast Pickle, began in March 2005.
John Edwards was the first "national-level US politician" to host his own political podcast in March 2005 which, shortly after included all the extras: a website with subscription feeds, guest appearances, Q&A from the audience, and more. Later that year, President George W. Bush entered the podcasting scene as well when his weekly radio addresses were given an RSS 2.0 feed for the purposes of downloading. The German chancellor, Angela Merkel, was the first head of government to issue a podcast in June of 2006.
Pod and vodcasting became quickly popular by way of being spread around the Internet via weblogs. On September 28, 2004, Google tracked 24 hits for the word "podcast." Two days later there were 526 hits, and three days later, there were 2,750 hits. Just under two years later, Google tracks 345,000,000 hits for "podcast." You could say the popularization of the concept happened pretty quickly.
The first Guinness Book of World Records award was given in February of 2006 to The Ricky Gervais Show, which is produced by Guardian Unlimited and hosted by Positive Internet. It has averaged 250,000 downloads for each weekly episode.
What is considered to be the world's first live podcast theatrical event was held on February 24th, 2006 in Ormskirk, West Lancashire, United Kingdom, at The Rose Theatre.
