The £23 billion raised so far by Lottery players for a variety good causes is being celebrated through a new viral film and social networking competition created by Momentum.
The campaign features author and comedian Danny Wallace, who talks about the viral competition, and shows viewers how not to make a viral.
The viral will be rolled out across sites including Facebook and YouTube, and will also have its own dedicated You Tube channel.
To support the campaign, a compeition will also be held, which asks users to talk about what Lottery funding means to them.
The person that comes up with the best idea will have their concept made into a film by BAFTA winner Nick Hamm.
