Answer:
pulsing, continuous, and flighting
Explanation:
Pulsing incorporates flight as well as constant scheduling throughout the year utilizing a lower level of ads with strong advertisement during peak sales times. Categories of goods sold during the year but experiencing a increase in revenues at irregular intervals are strong contenders for pulsation.
Continuous media cycle is working smoothly with little change. Advertising can sometimes be strong or weak throughout the whole period (maybe a advertisement appears on Television once every week, or even on radio 3 occasions a day), but the idea was that the cycle stays consistent throughout a referendum campaign or even all year round.
Flighting refers to an advertisement scheduling technique that oscillates between operating a regular advertisement program and terminating all runs entirely. Flighting relates to the duration during which advertisement is performed, while the time of suspension is defined as a break.
