Lobby groups and protest communication

I suppose that an interesting thing to think about is who would benefit from a history of ephemeral and interest group political communication within Australia? There is the process to consider ie.. How has political communication penetrated the main stream and how has it been successful? Lobby groups and radical groups may fine this information of benefit because they may not have the money to penetrate the mainstream media. There are also success stories to consider. ie. What was once a lobby groups or a radical group may now be the mainstay of mainstream political communication. And an interesting issues to consider is how has public culture facilitated political communication especially in terms of newer communication mediums such as the Internet. How is public culture being protected as a means to facilitate protest and ephemeral communication which is a vital component of a vigorous democracy?
