Talk Shows are an easy-to-produce format that is inexpensive, allows people to participate in the government channel, and are popular with today's viewers. This format allows a variety of guests to participate with little preparation as the topics generally consist of people's opinions. Talk shows requires little preproduction because the talk show is commonly about a topic that the guests are invited to speak about and are familiar with.
However, talk shows run the risk of becoming dull quickly if limited to "talking heads". Talking heads are visually poor, and viewers loose interest quickly. To add diversity in the discussion format, include field footage or live call-ins. Talk shows tend to dominate certain time slots and have strong followings. The key seems to be a central figure with a specific format, making a good host essential. A good host will be confident in discussing timely and controversial topics. An entertaining host can liven up the show by creating a fun atmosphere or by heightening the controversy by provoking guests and exaggerating viewpoints.
Since talk shows are so popular, it is important for a government access channel producer to review how network talk show hosts liven up their shows. You can look at popular, highly rated talk shows, and analyze the little things that make the program interesting. Then consider applying what was observed to your talk show format. Consider similar ways of adding "sizzle" to your shows.
Talk shows deserve considerable work. Ease of production, low cost, and maximum viewer potential are the major issues to consider.
