Podcasters Paul Colligan and Alex Mendossian have announced PremiumCast, a new service that lets you manage, deliver and sell podcasts and video podcasts.

The service lets you create custom messages, track subscriber usage, monetize podcasts and publish both public and private podcasts. Three levels of service are available: Free, Professional ($37/month) & Viral ($67/month). The paid options add additional features, including subscriber management and ecommerce capabilities.

“The normal paradigm for podcasts is one feed for everyone, so everyone hears or sees the same content,” said Colligan. “With PremiumCast, you can target personalized content to individual users.”

According to Colligan and Mendossian, the ability to deliver custom content to users will allow podcasters to monetize their content in ways that are impossible with traditional media. As an example, they cite Marc David, an early user of the system, that is using it to deliver personal motivational messages to the individuals who subscribe to his fitness program. Colligan and Mendossian also expect that customization will lead to greater retention of listeners.

The official launch of PremiumCast will take place during the upcoming Podcast & New Media Expo, where there will be live demos of the new service.
