you must consider the following points.

-promotional benefits of the song or album

-purpose of the music video to artist or group

-how does the music video generate money for the record company

-extention of income-release of the music video, advertising.

-producers statergies ie youtube, vevo, social networking

-synergy- promotion for the film industry

promotional, this attracts a wider audience to buy there album, they do this by producing a very mainstream genre at the time, however the song that is produced could be completely different to the music on the album.an example of this would be the Notorious B.I.G when the album Ready to Die came out. he made a track called Juicy, this was to grab the audiences attention in oder to promote his album.

purpose, this can be done for charity in order for people to buy the song and the money goes to the charity the song is about/ made for. and example of this is band aid "do they know its christmas". this song has made a lot of money for there charity. however there are other was to make money and one was is through youtube via adverts. advertiser will pay the song owner so that they use there advert at the start of the video.

extension of income- this can be done in many ways, one for example is the name of the song itself, (Migos-Versace, Ace Hood- i woke up in a new buggati) another way would be to show an artist wearing / using the product an example of this would be "Stormzy-Shut up" which features Adidas and "Ty Dollar Sign - Or Nah?" which features the famous beats pill at the begging in of the video.

producers strategies. often a producer will reach out to social media sites in order to promote the advert. a good example of this would be youtube, this is because even some of the most famous artists that are around now were discovered on youtube , therefore if people can be found of youtube this means you have a huge audience to advertise to.

synergy- this is where a song is made for a film/ tv show, an example of this would be the Charlie Puth song see you again made for the final fast and furious seven. often film makers will contact artist in order to make a song for an upcoming film. this is so that a connection is made and when you hear the song you want to see the film.

-the purpose of the music video

-was is extension of income for a film or for the artist or group

-find out where the video outlet is i.e. youtube, music channels.

-what were the sales, for cd sales and downloads

not only being one of the highest sellers of singles in history, this song and video influenced most of the music produced to date. this is the music video that finally took down the racist owners of mtg that did not want to play any videos featuring black performers. the purpose of the video was to tell the story of a grouped that micheal encountered that claimed to be carrying his or one of the jackson brothers baby. it was also to boost Jacksons carrer however he didn't realise it would catapult him to becoming the "king of pop" . Jacksons billie jean also helped advertise his album thriller which eventually became the biggest selling album of all time. the only place you can really find this video is youtube and the official Michael jackson website. the total amount of sales went though the roof selling an incredible 51-65 million copies .

consider the following points for each era

-the artists image

-music itself-fashion trends-quality of the footage

-types of shots

-editing techniques

-special effects

-styles

the music itself in the 1950s was very much the era of rock and roll, i also feel that this song ties in well with the era considering this genre dominated the charts so much. however R&B really influenced the rock music back in the 50s. this was also the era of the one and only Elvis Presley who dominated and influenced the world with his music. he also introduced the fashion sense of rockers, this meant Motorcycles and Leather jackets with slick back hair, which elvis had for a number of years.

there are a fare few shots but they are very basic close ups of his face or a long shot of the whole band, this was to keep it simple when it came to editing because there was no fancy cgi it was littereallly cut and stick in 1950.

as you can see there are obvious jump cuts that are so sharp, however they do go in time with the music video. the main style of the video is fairly standard and in black and white, these were to only tv shows formats available.

during the 1960s we were introduced to bands like The Beatles and The rolling stones, these were two of the most influential bands of the time for fashion and music, these two bands laid down the paving stones for most modern rock music today. the rolling stones were very influential with there famous tounge logo. this is still seen in todays world from Tshirts to even artwork.

i feel that the quality of the footage was much better as you can see there are no marks or scratches that pop up, you can also notice its a lot more fluent in the way that the tape rolls, its not jumpy at all and can be considered a lot more of a music video style compared to Chuck Berrys- maybellene.

the types of shots that are used throughout the music video are not faded and no fancy transitions are used, it is simply just cut, however i feel that this works very well due to it being in time to the rhythm of the guitar. the editing techniques used for this would have litterally been cutting the tape, and sticking it to another piece causing the camera location and zoom to change.

during the 70s a lot of music shifted toward disco music, however rock played a huge part in the western region of music, having said that punk rock played a huge parts in the chart with it thriving forward throughout the century. during the 70s the jacksons were introduced, and as we know now nearly all the members of the jackson5 were successful.

as you can see the music video now has colour and much better video quality, this helped the music era as it pushed sales as the performances looked more appealing to the eye when televised. the music video itself features elements from the sixties but however has progressed a huge step forward as even the introduction shot was a pan. this also features shots of the camera cutting away from what seems to be them performing to random clowns at a dinner table, this was a step in the right direction toward making more successful music videos. 

as from what the eyes can see, not special effects were used apart from make up, however this would have been done in the pre-production before the video was filmed

due to dance music going out of fashion in the early years of the 80s a nw era of music arose such as post disco, italo disco, and dance pop. however the Rock seen carried on being enjoyed by millions in which another genre of rock was born. Thrash Metal, however this was brought up into the underground scene but wasn't made popular until later on in the 80s, some of the famously born thrash metal bands include Metallica and Slayer. the 80s was also recognised for its increased use in digital recordings, synth pop and electronic was also enjoyed for its non traditional instruments. this drew in peoples attention in the same way it does today.

throughout the use of the 1980s instruments and the way songs were edited was a huge pushed due to the amount of new sounds and genres emerging people came up with numerous ways to record in edit, some methods we even use today.

i feel the music video had tons of different camera angles, mainly using pan shots and zooms, i feel that the quality of the video is improving throughout the years, this is obvious tho as technology evolves throughout the years the quality so will the quality. i feel that the editing in this music video is excellent, it features smooth transitions and an unrealistic twist when a comic comes to life. this really grabs your attention as it was really abnormal. for this affect they would have used a green screen and then would have edited the video on some form of computer.

This music videos era was where Rap music was finally being played on the radio alongside other rappers like Tupac and Snoop Dogg. i felt that Biggie was a huge inspiration to how certain people dressed, this was when Gangster rap and hip hop changed fashion to even how some people dress today, not only did rap music and especially Biggie change the way people dressed, he also changed the way people thought about the law, and what they was doing with there life.

the 90s was famous for its talent of Hip Hop, R&B and Rap it became to be very successful and popular throughout the decade. however like the 80s Rock was still a high demand genre even more types of rock started being produced such as grunge, indie and even alternative rock. but if we take into account the world a large part of it started to enjoy the more Electronic side Including Drum and bass and even Garage. throughout this time period everyone in London and even throughout England wanted to be an MC (Microphone Controller) this you could say was a huge trend set.

i feel that the artist in the video tried to show how he has come from rags to riches, you can see this when he is standing on a door step in brooklyn wearing a basketball jersey, jeans and timberlands however if you look when he is in a nice mansion he is has changed the outfit to a completely white suit.

the types of shots used are excellent with the lyrics. this is because it completely ties in in with what he is expressing with what he is saying in his lyrics. the editing in tho video i thought was done very well which featured slow motions. after looking at videos from the 90s this is the only one i could find that even feature any form of slow motion.
