None of this explains why there aren't left-wing talk radio stations.
To figure out why left-wing talk doesn't work well on commericial radio, you need to consider the close to 800 NPR affiliates out there. Granted, not all of them carry the various public radio talk shows. Granted, NPR is not as extreme as most commercial talk radio, as it is generally center-left as opoosed to the far right one associates with commercial talk radio. However, the existence of NPR seriously degrades the commercial viability of left-wing talk because a large portion of the potential audience is already listening elsewhere. NPR doesn't explain by itself the preminence of the right in commercial talk radio, but it does help to explain it in part.

Good point, Ernest. The nature of the imbalance in talk radio is an entirely different question than the conditions that allowed bias in the broadcast media. Why did almost exclusively conservatives enter the talk radio market after 1987, especially after the early 1990s when it became apparent that it was a highly successful medium?
The only reason NPR has captured a lot of the liberal market is because they are the only major show out there that is not conservative. Yes they lean more to the liberal side than conservative. However, they generally do not see themselves as primarily a political commentary or a political station, or primarily out to spread the liberal viewpoint, which is what differentiates most of the syndicated talk radio shows ont he right.
So were liberals just not interested? Did the owners of the bandwidth licences or the distributors of the licences have some ideological bent themselves? I have no idea.
In addition, not mentioned by the article, another thing that made possible the growth of talk radio was the migration of former music channels to FM freeding up AM bands for talk.
I have two or three questions however:
1 Why did Clinton not appoint FCC commissioners who would reinstate the fairness doctrine? In fact, why did he appoint Michael Powell, who has some rather extreme deregulationary policies opposed by most of Congress?
2 Why did Congress not pass fairness doctrine legislation in 1993 after Bush Sr.'s veto threat had been removed?
Anyone who can answer these two questions is a genius.
