2. What is commercial television
 Commercial broadcasting is primarily based on the
practice of airing radio advertisements and television
advertisements for profit. This is in contrast to public
broadcasting, which receives government subsidies
and eschews most (or all) paid advertising.

3. Advertising
 Advertising is a form of communication for
marketing and used to encourage, persuade, or
manipulate an audience (viewers, readers or listeners;
sometimes a specific group) to continue or take some
new action. Most commonly, the desired result is to
drive consumer behaviour with respect to a
commercial offering, although political and
ideological advertising is also common. This type of
work belongs to a category called affective labour.

September 1955, advertising Gibbs SR toothpaste.
