Audience segmentation is something media industries do to split society into bits or “segments.”
This can be done through demographics (age, gender, sexual orientation (sexuality), ethnicity, occupation/class)
Geo-demographics = Where you live
Psycho-demographics = Lifestyle choices e.g being vegetarian, smoking, driving, owning a dog are some psycho-demographics.
Acronym = An abbreviation formed from the initial letters of other words and pronounced as a word E.G. NASA, BOGOF & MILF.
Or the first two letters e.g. OFSTED is Office Standards in Teaching and Education.
