The campaign will see animated characters including celebrities and members of the public ‘march’ across supporting websites including Google, YouTube, Facebook and AOL on 15 November.
The march aims to deliver a petition to the Government to create a Bullying Commission for the protection of children and young people from bullying and harassment.
Celebrity marchers include Aston from boy band JLS, girl group The Saturdays and Michael Parkinson.
Members of the public can sign up online and create their own Big March avatars to join the march against bullying.
Frank PR founder and MD Andrew Bloch said: 'The Big March is an online first and I’m proud to have all the mini marchers coming across Frank’s website on the day of launch. It’s a great cause.'
