The media is not controlled by the FCC in the way you imply. There is no evidence of it and to suggest it is ridiculous. It's accurate to say it's controlled by corporations, who have their own reasons that do seemingly align very well the status quo of current politicians, but that's not to say the news media is in any way coerced. There are plenty of simple, rational reasons why this would be the case.

The reason you see the same lines from channel to channel is because these news outlets buy their stories. They are pre-written and arranged and often include video footage. They do this because original reporting is expensive and it's silly for a hundred reporters to cover the same unimportant subject when a single person can do it and sell it to others. Everyone wins, but it does result in many places not altering the script very much to make it more original. To suggest this is a government plot is silly. Again there is no evidence of this.
