I did some checking and found that the history of the television broadcast industry in Canada shows a great deal of entrepreneurial spirit. The following link is a rather candid account of events from the late 1950's to the present:

However, I think the above account leaves out some extraordinary facts - all political. Prior to 1987, Canada was a Dominion of Great Britain, all private television stations were required to follow the operating practices of the CBC, collectively called the Dominion and Transcanada Networks - that included all private affiliates. Not exactly what you would call free enterprise, but controlled enterprsie ...perhaps even socialist. In other words, unlike the good'ol USA at that time - the political and constitutional laws were not in place in Canada until approx the 1970's to allow private stations to take a leadership position to introduce new technologies. Additional information is also available from the CBC archives. Here's an interesting URL for reference:
