Yes there are entire programs and agendas built around constructing and distributing IMD ( information,misinformation and disinformation ) and many of these are purposed for exactly what you believe,as well as for other purposes.
We have always lived in a world of IMD but it has accelerated at a almost logarithmic rate with the advent of the internet and cell phones with 24/7 access to media.
If attempts at self regulation fails ( which appears to be working right now ) then I'm sure we will see attempts to regulate the media in the future. More and more people everyday are questioning and challenging media's as to there content,presentations,political affiliations and sources.
Personally I believe the 4th estate (mainstream media ) has failed its purpose as the voice of the population in the USA. The MSM today is basically just a proxy propaganda arm for political agendas. It can redeem itself, but a lot of change will have to occur before this redemption.
