"This galloping concentration in broadcast ownership is unhealthy"

Byron Dorgan's quote is referring to the increasing concentration of broadcast ownership in the media industry. This implies that a couple of big business are managing a large part of the media outlets, such as television, radio, and newspapers. This can be seen as unhealthy due to the fact that it restricts the variety of voices and opinions that are readily available to the general public. It also offers those business a lot of power to shape popular opinion and affect the public's access to info. This can lead to an absence of transparency and responsibility, as well as an absence of competition in the media market. This can lead to a lack of development and a lack of quality in the media that is offered to the public. Eventually, this concentration of broadcast ownership can result in a less informed and less engaged public.
