Advertisements are a necessity. Do any of you know how much it costs to produce broadcast content? I do I work in that industry. So many of you think its greed greed greed but its not. More things happen behind the scenes to secure rights to programing than you would think.
Advertisements are only a necessity if you are giving away the content. HBO and Showtime, for instance, do just fine producing original TV content that people pay to watch.
There is plenty of greed that goes into the cable bill. Greed of local stations that charge cable companies to deliver OTA content that consumers can receive for free with an antenna. Greed of satellite providers that only sell packages of channels that customers can't pick and choose which are forced on the basic tier. Greed of municipalities that charge the cable companies for running cables through your property. Greed of the cable companies that basically have had a monopolistic position.
