The goals of today’s talk • Give an overview of the video case study • Look at today’s changes in historical context • Present a framework for video platforms • Examine current competitive dynamics among video services • Discuss future trends
Overview of video case study • The evolution of the U. S. TV industry can be broken down into three phases – Original broadcast model (1930 s-1940 s) – First reinvention of television (1940 s-1990 s) – Second reinvention of television (1990 s – present) • Each phase includes a combination of – TV extensions – New delivery platforms – New content providers • General trend towards value chain fragmentation • Today’s video landscape is messy and complex, and changing quickly
The original broadcast model • Simple TV service model – networks produce content – deliver content over licensed spectrum – linear programming, no interactivity – ad-supported service, free to consumers • Dominated by big three networks (ABC, CBC, NBC) • Vertical integration of production, content aggregation & delivery TV Big 3 networks OTA
The first reinvention of television Cable VCR – retransmits broadcasters signals (1940 s) – imports distant broadcast signals (1950 s) – Cable content industry is born (1970 s) – late 1970 s – time-shifting, ad-skipping, trick plays – on-demand retail channel Satellite – Direct-to-home systems (1980 s) – Distributes cable & broadcasters programming New content providers New delivery platforms TV STB Satellite TV Cable TV networks STB Cable TV Recording VCR Big 4 networks OTA VOD (movies) New delivery platform for movies B&M Film studios

Will Web TV compete with or complement carrierbased TV services? • “Unbundled value chains innovate faster. The Apple’s and Microsoft’s will provide experiences, not pipes and will be more agile than the network operators who provide more integrated services. ” • “The user has become the master. Consumers know how to put together their own bundle of services. It doesn’t have to be an integrated solution. ” • “We’re starting to see the tail wagging the dog – the terminal is driving consumer choices. In the future, Sony and Samsung will have TVs connected to the Internet. People will buy devices that happen to connect to content. ” • “At the end of the day, most people buy bundles of services. The consumer will buy the least costly package. ”
