There are four types of radio:

• Digital Radio
• Satellite
• Low Powered Radio Stations
• Internet

There are many different purposes of radio shows. Some play music, which varies on genres as some play chart music while others specialize on regional music. Some radio shows have interviews, cover news and weather, play radio show games etc.

The two types of radio are commercial and non profitable.

Commercial radio focuses on making a profit from their services, so they will target specific audiences and play many adverts during their shows to make profit and pay for their station.
A non profitable radio station would be the BBC, which is paid by the public and focuses on giving non biased information and wants to reach as many people as possible.

Public - These radio stations provide a wide range of channels and shows to appeal to all type of listeners. They are in most cases publicly funded, so they can spend a lot of money on providing good content and constantly increase quality.
An example of this would be the BBC, which is publicly funded via the licence fee. They are non profitable and use all the revenue to improve their services to appeal to as many people from the public as possible, which is why they offer such a wide amount of radio stations and different types of speech packages.

Private - These are commercial stations which serve regional or local areas. Their main source of income is from advertising and are not funded by the public. Because of this they do not have as much money to spend on providing as wide of content as public, and often enough these radio stations have very few people working there. They are often music station as it's cheap to offer music and is why they offer very little to no speech packages.

Community - These stations are also privately owned, often by big corporations. Due to this they are also limited with content and try to target very specific audiences. Their main source of income is from advertising and are often paid to air paid programming. They are very similar to private radio stations, their one big difference is that a community radio station would be something like a college radio station. TFM would be an example of this.

News Packages

These tend to be formal and be straight forward, dependant on the radio station it can be biased or unbiased.
These packages provide in depth information on current news, this can be local, national or international news.

Name of station: TFM

Name of show: 10 o'clock news
Target audience: 25-44 year old females from the North East

Genre: News

Style: Semi-Formal and very fast
Structure: Cue, jingle, sports, news
Contributors: Presenter and interviewees
Legal/Ethical considerations: Has some sensitive topics, make sure to warn before hand in case there are minors present.

Statistically more females listen to radio than males, as they might be driving their kids to school or be out shopping, therefore they target females and start off with sports in hope that they will talk about what they heard with their partners. Because they might be with younger children, the radio station has to make sure to warn before reading or explaining a sensitive headline so that the radio can be turned down/off to make sure the children don't hear anything they shouldn't.
It also starts off very fast and with catchy jingles to attract the attention of the listener, it won't be boring as the content constantly changes and stays interesting.

Factual Packages

These can be either formal or informal. These can also range in style of music, documentary or discussion. Their main purpose is to entertain but also tend to be quite informative, often enough they will have well edited sound effects, music and cover good and interesting stories.

Name of station: BBC Radio 2

Name of show: Thirty Years Man and Boy - A calmer Chameleon
Target audience: Adults, Boy George fans

Genre: Documentary

Style: Informal
Structure: Jingle, introduction from presenter. Plays background music while interview play over it.
Contributors: Presenter, Boy George
Legal/Ethical considerations: Interviewees shouldn't have any of their information revealed to the public. Make sure to have adequate permission for music used.

This package is mainly targeted at adults, who know of Boy George, because of this, Boy George's voice doesn't need an introduction, as well as the whole package itself, as from the music use for the opening and background music the audience should recognise it and automatically tune in and remain entertained.
The speech package plays the piece of song which an interviewee might be talking about to attract audience as they will know the song and will stay tuned in. It is also a good method of giving nostalgic feelings to the listener which will make them want to continue listening.

Target Audience

A radio speech package will be entirely based on the audience it is targeted at. The audience could range from age, gender, demographics, background or even geodemoraphics.
The style and type of package will be dependent on the target audience and who it is trying to appeal to. 

Ethics and Regulation

There are many different rules set to regulate the airing of radio shows. Ofcom is responsible for the radio industry, and have therefore set a broadcasting code which is to be followed by the producers to prevent harm and offence to the public. 

The 10 sections that make up the Ofcom Broadcasting Code are:

1. Protecting under 18’s
2. Harm and Offence 
3. Crime
4. Religion
5. Due impartiality and due accuracy and undue prominence of views and opinions
6. Elections and Referendums
7. Fairness
8. Privacy
9. Commercial References in TV programming
10. Commercial Communications in Radio programming

When it comes to ethics it is a little harder to regulate as people view things differently and have different opinions on things. If there are too many complaints about a particular radio show then Ofcom can deal with that accordingly, even if it doesn't break any of the codes. The main point to keep in mind when it comes to ethics is that the producer should avoid offending anyone in particular.
