There is no universal rule about using an article (a or the) in front of the name of a broadcaster.
Some broadcasters are always introduced with the. It's the BBC and the SABC (South African Broadcasting Corporation).
The US channels on the other hand are usually referred to in my experience simply as NBC, ABC and CBS unless their full names are spelled out, when the precedes them.
NBC advises people to go to NBC News, not the NBC News.
While I'm not clear as to exactly what you mean by advertises the p, the answer to your question is that it depends - both on the channel's usage and on popular usage.

Since "news channel" is not capitalized, I read this as:
In the first scenario, suppose that the news channel (that is named) PBC advertises the p.
In such case, use the, since news channel is not a proper noun.
However, if the broadcaster was named "News Channel PBC", then no article is used.
