On the last point, the commission looked at it at various times in the past, the last time in detail almost a decade ago, and at that time the impact of broadcasting being delivered by the Internet did not have as significant an impact on the broadcasting system as it clearly does today.
It's an interesting question you pose. I suppose the simple answer is that regulation is not always welcome by parties. There are groups today that are subject to regulation and have obligations, if you will. They operated in a walled garden in the past and the walls have disappeared.
The new players have entered. They were not subject to similar regulatory obligations and what is on the table now is that we should find a regulatory framework that treats all of those who are engaged in broadcasting...be subject to an equitable broadcasting regime that is fair to all.
