Charity

Every year the Yogscast host a series of livestreams in order to raise money for charity. Starting with the month of December they begin playing games and generally interacting with their fans; all the while attempting to get donations for their efforts.

Whether it's playing video games, singing karaoke, or just goofing around, their videos bring smiles to the faces of over 20 million subscribers on YouTube. They use that popularity along with a seasonal schedule to help fund various charities like last years holiday livestream The Yogscast Jingle Jam. 

Their success is due to a few factors: It's once a year, it's the same time every year, and the way they accept the donations allows a certain level of exclusivity to the donator. First off, the live stream is always the month of December, from the first to the thirty-first the fans are treated to something that they will not see any other time of the year, interaction between all of the Yogscast family. While there is usually crossover between similar channels, fans of multiple members of the Yogscast may never get the interaction between members that they would like. During the Jingle Jam that interaction is a complete uncertainty, anyone may be on the stream any given day. They may have a set schedule of members who will be streaming, but any member of the Yogscast can and will join in. Add to that the fact that it's the same time every year and you've given fans something to look forward to, a countdown to something different, something they enjoy. 

The way they accept the donations gives them exclusivity in that, when a donation is made their name and a message will be sent to the current streamer and if the amount is high enough ($5) the streamer is obligated to give the donator a shout out. By being paired with the charity video game site HumbleBundle.com, they give something back to the donator, a bundle of video games on top of that warm feeling that comes by helping those in need. Their strategy seems flawless, fans donate money to charity and get free video games to play and a livestream to watch. It's a win-win that leaves everybody happier during the holidays.
