2.      Since TV PSA is visual, storyboard is really crucial to indicate the sequence of picture action, camera angles and cues, dialogues, sound effects so that the image for one TV PSA is much clearer with the help of storyboard  and as opposed to radio PSA, I personally think storyboard is not that crucial as radio is audio and the focus is mainly on audio and sound effects. 

3.      The target audience for both TV and Radio PSA may vary as radio has their own specific listeners with the music genre they offered, hence Radio PSA should match with niche radio listeners according to what their interest may be meanwhile target audience for TV can be wider than radio and so I think TV PSA can be more open in which it should be suitable for all range of ages to watch. 

1. First, based on the time taken for both PSA. Radio PSA are usually will be on 20- 30 seconds long while for TV PSA it will take on 1-2 minutes long.

2. For the second differences for the radio PSA and TV PSA is, for TV PSA it needs more drama, music, and other techniques which involves visuals that can be used to persuade the audience. Meanwhile, for the radio PSA, it is more to audio only which is the message will be direct to the point and simple.

3. The third differences for radio and TV PSA is, since TV PSA needs an visual and acting from the actor, it means, there must be skills, the talents, the hard work for the editing and creativity to create an TV PSA. In the meantime, for radio PSA it only needs a creativity for them to write a catchy story since radio PSA only require people to hear the audio.

1.       TV PSA is intended to sell products or services for a profit-making advertiser whose purpose is to promote their product or service to attract buyers while Radio PSA aim to raise public awareness about health and/or safety issues that is made on behalf of a non-profit organization.

2.       For TV PSA, visual material must be included to get a good approximation for television, while Radio PSA only include audio. 

3.       TV PSA are usually 60 seconds long, while Radio PSA up until 10 seconds to 30 seconds based on number of words

1. The first difference is the duration. TV PSAs are usually 30 to 60 seconds in length while radio PSAs are a bit shorter which is 10 to 30 seconds.

2. The second difference is the requirement. TV PSAs require visuals such as pictures and videos that include a scene that could implement the message to the audience while radio PSAs only require audio which the messages are delivered direct to the point.

3. The third difference is the cost. TV PSAs are high cost to write, produce and distribute since it require payments for actors and tools purchases while radio PSAs are low cost since it only require a voice recording and sound effects.

2. Radio PSAs duration only last for 15-30 seconds while TV PSA last for 1-2 minutes.

3. TV PSAs require more budget and funding in order to pay for an actor and setting equipment than radio PSAs. This is because radio PSAs just just using a voice and background effect. This is shows that the radio PSAs are less budget compared to TV PSAs
