The basic themes follow, but 1st some useful Ppts, which may be swapped out for updated versions over time:
Merch metallica from DB3igs
MUSIC VIDEO HISTORY + PROTOTYPES
in a nutshell, read the Austerlitz book which is specifically on this point. There's an extensive history before MTV made them a default promo device, going back decades earlier than even the key archetype (The Beatles 1960s film A Hard Day's Night).
ANALOGUE FORMATS: RISE AND FALL
show understanding of how the music industry has undergone changes before digitisation. Sheet music was the revenue driver a century ago, with gramophone records slower to become dominant. Vinyl became notably dominant with the rise of the teen as a distinct demographic with disposable income in the 1950s. Cassettes slowly rose as a rival from the 1960s, becoming the biggest format by the 70s/80s - especially when the Sony Walkman hit. Vinyl and tape sales slowly collapsed as CDs kickstarted the digital revolution in the 80s ... but have taken on hipster coolness and are ironically zeitgeisty - why?
DIGITAL MARKETS: CDs, CRAZY FROGS, PIRATES + NAPSTER, SPOTIFY...
Carefully + specifically establish when + why the music industry's global revenues peaked, and why they began falling again ... until very recently they've finally began rising again. Consider the piracy issue, engaging with web 2.0 as you do. Explain how UGC eventually became a revenue-raising tool for the record labels. Look at the controversies over payment rates, and how radically they differ across platforms. Do a case study of 1 or more acts with music on multiple platforms (like my Bicep case study).
MODERN REVENUE DRIVERS: MERCH, TIX ETC
While vinyl's high price means low sales do bring in useful revenue, look at how merch (analyse the range of items for some bands + how these usually reflect a wide audience IF they're for big or older/long-established acts like Metallica), live concerts (VIP tix etc), licensing (games, TV, film) + sponsorships now bring in most of artists' income.
BANNED IN THE USA: CENSORSHIP + REGULATION
There is limited formal regulation, though the BBFC (UK) do have a voluntary system, and YouTube at least notionally apply an age-rating system - plus the parental advisory/explicit lyrics stickers in the US. Just like the film industry, the music biz has faced times of extreme governmental/political pressure fuelled by the press: the 80s metal/rap moral panic leading to hearings (and arrests for selling a 2 Live Crew record); the Dixie Chicks and Beatles record-burnings from different eras; the Gulf War radio blacklist of songs about war ... and peace; Elvis wiggling his hips; UK grime artists effectively banned by the police
OWNERSHIP: INDIES AND BIG 3
Just how dominant are they? How can Indies compete? This is a very similar issue/debate to your AS film industry learning - online/social media + crowdfunding + self-distribution + self-marketing [AM's use of MySpace a great early archetype] are all important.
