Historical perspective of Anti-Broadcasting

“Anti-Broadcasting” is not a well-known word but its concept is one of the most important issues in broadcasting. “Broadcast jamming”, “broadcast interference”, “blocking of broadcast” are some other similar phrases that are used interchangeably. Based on my empirical experiences, I think if we don't pay enough attention to “Anti-Broadcasting” issues, we won't be able to study about broadcasting efficiently. So I have initiated a historical review on this subject from the first time that anti-broadcasting has happened until now.
