A live, unscheduled webcast (note: webcasts are sometimes referred to as streams) that is initiated with minimal promotional efforts, such as a single Twitter post.

A stealthcast allows for a highly personalized and interactive session with a sparse audience. Participants are typically those individuals that are persistently logged into an IRC chat room associated with a specific webcast (enjoying ongoing chats while also hoping to catch a stealthcast), as well as those who joined based on viewing the minimal promotion, either by polling a website, using a third party program for alerts, or by receiving notifications via their mobile device.

The phrase 'stealthcast' was started by YouTube and uStream content creator, Alfred, who wanted to reciprocate a 'thank you' to those monitoring his IRC chat room with a live webcast while also having a personal, interactive session with a small and selective audience.

An Uber Stealthcast is a Stealthcast that is launched with absolutely no promotional efforts.

Whereas a Stealthcast will typically have one type of notice, typically a singular post via Twitter, an Uber Stealthcast will have no notice.

Specifically, it is a very low-key webcast, typically catering to a small audience that may be in the IRC chat room associated with a video feed.

The phrase was started by YouTube and uStream content creator, Alfred, who wanted to reciprocate entertaining video content, via a webcast, for those who were tirelessly monitoring his IRC chat room.
"Holy cow, I didn't even know he was doing a Stealthcast, I didn't see a post on Twitter!"
"That's correct, he didn't post one. It's an Uber Stealthcast"
