For a long time their was a massive licensing fee on clubs and venues in Sydney this meant that only the very big clubs in the city could afford to have a liquor license. On the other hand Melbounre has had low liquor licensing fees which has meant that a lot more smaller venues could have a liquor license.
I think this works as a great analogy for what social media does to a media landscape, it offers partons more options and it offers (music) artists more channels and a chance to grow slowly instead of having to break it in the big time first. Look to Sydney to start producing a number of better artist.
A little video that I made about the changes.
