The most trustworthy source of information for me is the local news. Cable news seems to have their own agenda whereas local news is providing content on communities. Local news provides weather, traffic, information about schools, crime and community outreach. The reason I believe cable news has their own agenda is because their owners have deep pockets and are constituents in the political realm. That gives them the power to control content and put a spin on the information. There are a lot of advertisers that do market research on what viewers want to see. I found an interesting article about the biggest advertisers on cable news channels.
Looking forward to your thoughts.
