With recent discussions of current market voids, what voids do you believe may be best filled using HD 2 channels? Additionally, how do you believe may be the best marketing approach to promote consumer / listener accpetance of HD radio, making it viable and creating a demand for the medium? Remember, FM was, for the most part, widely unaccepted until the 1970s before FM popularity and demand skyrocketed in the 1980s. I believe currently WUFT-FM, WSKY, WNDD and WKTK are the only stations currently utilizing their HD 2 channels. If there are any I have miseed, please added them, along with HD format, to the list.
