Final answer:
The third type of television coverage used by campaigns, besides political advertising and news management, is participation in debates or forums. These platforms provide candidates with a chance to present their policies directly to the public.
Step-by-step explanation:
The three types of television coverage that campaigns use include political advertising, management of news coverage, and debates or candidate forums. Political advertising is the paid media space candidates use to promote themselves. Management of news coverage, often referred to as 'free media', involves strategies to influence how campaigns are reported in the news. The third type of television coverage is the candidates participating in debates or forums. These are opportunities for the candidates to discuss their policies and answer questions either from moderators or the public.
These forms of television coverage play a critical role in shaping public opinion and informing voters. Each approach has its strategies and impacts, and candidates and their campaign teams work diligently to maximize their effectiveness in conveying their messages through television.
