Why is that leftist bias doesn't prosper in radio, while the right thrives?
fistful, your next sentence actually provides an answer to your question:
The left does well everywhere else: television, print media of all types (newspapers, novels, magazines, poetry, academic writings, etc.), feature films, live theater. Even visual arts like painting and sculpture seem to be a left-wing field.
The way I see it, there's only so much market for a left wing message, and Air America is competing with CNN, MSNBC, ABC, CBS, NBC, and most big-city newspapers.
Even a devoted lefty can't listen to the radio AND watch television AND read the New York Times simultaneously - he has to make choices, and Air America was just ONE more choice among many left-wing sources.
Conservatives listen to talk radio because there is little to no competition in the dominant media to attract conservatives, other than the middle-of-the-road Fox news channel . . . which is denounced as "right wing' simply
because they actually
do make an effort to show both sides.
To use a fruit analogy . . . suppose your local farmer's market only has fruit vendors that carry apples, and each offers only one type of apple, with the varieties Red Barron, Fireside, Golden Delicious, Paula Red, Granny Smith, Red Delicious, Roman Beauty, Fuji, and Macintosh already represented.
Two new vendors come along: one offers Haralson apples, the other offers . . . oranges.
Who is more likely to do well?
