I try not to do a whole lot with Catholic Podcasts, as there are others who are focusing on Catholic Podcasts more and better than I, but if you've never been exposed to SQPN you might start now:

The Star Quest Production Network is proud to announce that three SQPN shows have won in various categories of this year’s People’s Choice Podcast Awards!

The Daily Breakfast, a morning show hosted by Fr. Roderick Vonhögen, won the award for best religious podcast;

Praystation Portable, daily prayers from the Liturgy of the Hours formatted to be used on mobile phones or other mobile devices and hosted by Jeff Vista, won the award for best Mobile Phone Formatted podcast;

Catholic Rockers, a podcast higlighting new Catholic popular music, hosted by George Leite, won the award for Best Podsafe Music podcast.

It is the third consecutive year that SQPN shows win Podcast Awards. In 2005, the Catholic Insider won the award for best religious podcast; in 2006, the Daily Breakfast, Catholic Insider and the Rosary Army podcast won awards. This year, SQPN also stimulated people to vote for Steve Runner’s Phedippidations podcast. Steve is a longtime SQPN listener and friend of the network. Phedippidations is the winner of this year’s award in the Sports category.

The awards will be officially presented to the winners during the Podcast and New Media Expo from 28-30 September in Ontario, California.
