I thought that the days of the podcast networks were over and we were firmly entrenched in the era of the "un-ntework", but apparently not.
To complete the tri-fecta, The Photocast Network has become the third podcast network to have the intials TPN (Tech Podcast Network, The Podcast Network and now The Photocast Network). This TPN is a network of photography podcasts and features such shows as:
Tips From The Top Floor
The Candid Frame
2 Minute Photoshop Tricks
The Simple Photo Minute
The Radiant Vista
Martin Bailey Photography
I'm not sure if I would call digital photography a niche topic since so many people are into it these days, but certainly the ideal of a photography only podcast network is unique. One thing that this network should be able to do very well is monetize the network. I can only imagine how much digital camera and digital editor software manufacturers would want to get their ads into such a targetted market.
