Wait remember Lou Dobbs of CNN and Fox he always acts like an objective reporter but he always insert his opinions to the clip.
This is nothing new, though I suspect it's more prevalent now. In the 50s and 60s, Los Angeles had George Putnam on KTTV and later KTLA. He was immensely popular, and was reportedly the highest paid news anchor in American - making more money for his local LA newscast than Walter Cronkite made at CBS.
Putnam's program always featured his official
"One Reporter's Opinion" editorial, but really, he editorialized frequently throughout the program, and his program was seriously slanted toward the right wing of American politics throughout. These days, Putnam would be very comfortable at Fox News.
Remember the Late Pete Wilson of KGO and KRON he played the Objective Anchor on the 6pm news on KGO ABC7 and KRON4 but saved the political commentary for KGO AM 810. Look at the Late Dave Mcelhatton of KPIX he was objectionable but on KCBS 740 he did his opinions there. Look at Brian Sussman who was at KPIX and KCBS 74 he was objectionable during the weather reports but is a big propagandist for the Tea Party on KSFO and So is Barbara Simpson of KTVU and KSFO.
Recto - I think you mean "objective" not "objectionable." All those you mentioned above maintained objectivity as TV anchors and reporters. They were certainly entitled to express their opinions in other forums - that's what talk radio is for.
Sussman is a bit unusual, in that he was a weatherman. It's hard to fathom how he could editorialize a weather report, except possibly to deny global warming.
Barbara Simpson didn't get into conservative talk radio until she was no longer a news anchor. George Putnam in LA also became a talk host after he stopped anchoring the news, but he was a well-known conservative while he was still anchoring.
I found this interesting clip on You Tube - from the short-lived program
Both Sides Now in which Putnam debated with comic Mort Sahl. While Putnam is in typical pompous form (you can clearly see the genesis of 'Ted Baxter' here), it's actually Sahl that gets carried away.
