> The stations on cable TV were always existing TV stations like WGN or TBS.
Hilarious. There were originally very few cable channels and generally you needed specialty hardware to even access them since everyone way on over-the-air transmitted by hardline or stuck with rabbit ears. WGN...TBS....those didn't exist alongside the Z-channel (1980s representing). What you mean by cable is a product of the last few decades where almost all signal is now carried by cable. The premium involved in that is now considered, incorrectly, part of the cost of transmission. The fact that it's not over-the-air should give you pause. It's now carried by cable, whereas cable was originally an extra premium cost for specific channels that....no surprise, had no commercials and pushed that (http://lmgtfy.com/?q=cable+no+commercials)
You're too young to know what you are talking about, since some of us were actually alive decades before the internet. Asking to prove the sky is blue, is transparently juvenile and ineffective at making a point (maybe it isn't blue?).
> You are a complete idiot. If I am wrong, cite some proof for your extremely stupid assertion.
This is about history, not some nebulous deductive assertion. It's very clear you aren't smart enough to make a basic observation without exploding into part and parcel nonsequitors....probably insults people throw at you, with proper context. Please let your guardian review your posts, in the future.
