– it has been estimated that it accounts for approximately 27-55% of all Internet traffic

(depending on geographical location) as of

and download & Server overloaded

– File Separation, Parallel Download.• Idea from “MojoNation” : split a single file into pieces

– Motto : Give and ye shall received

• Seeder : Original Source, Upload Only.

• Leecher (Peer) : Sender(Upload) and

Receiver(Download)

Bittorrent Conponent

• Client : Tracker Client Program

• Server : Collect Torrent File & Tracker

– Close System

• Member / Ratio (Upload / Download)

– Open System

• Torrent File

Advantage / Limitation

• Advantage

– Higher Speed

– Enable to transfer bigger file

• Limitation

– Speed depends on No. of peers

– Problem with streaming file

Why They can’t sue Bittorrent?

• if it can be used for legal purposes.

BitTorrent passes that test, says Fred von

Lohmann, a lawyer at the Electronic Frontier

Foundation, because Linux groups and

videogame companies regularly use it to shuttle software around the Net. "That puts

Bram in the same situation as Xerox and its photocopiers.”

Agenda

•P2P Definition

•Evolution of P2P

•Case Study Question and Answer

Case Summary: P2P Networks Rock

• Court battle: MGM Studios, Inc. v. Grokster, Ltd.

– June 2005: The U.S. Supreme Court unanimously

concurred that Internet file-sharing services such as

Grokster, StreamCast, BitTorrent, and Kazaa could be

liable for inducing copyright infringement.

– Business model: Steal the music, gather a huge audience,

and monetize the audience by advertising

• Legal victory!!! but do not solve problems facing the

music industry…WHY??

Case Summary: P2P Networks Rock

• Downloading legal music

• Business growth 50% per year since 2006

• Not strong enough to compensate for the plunging CD

sales

• Not downloading entire albums

• Downloading illegal music:

• Using file-sharing P2P networks

• Younger people

• Falling CD sales revenues

Question from case

Question 1

• How can P2P file-sharing networks make money if they do not sell music?

– Direct

• Sell movie online (e.g. www.cinemanow.com)

– Indirect

• Provide the download service for online game and earn from Air Time

• Sell advertising on the sites

• Distributed Software for advertisement to peer PC directly

Question 1

• How can P2P file-sharing networks make money if they do not sell music?

– Indirect (cont.)

• Member fee for Bittorrent website.

• Bittorrent Broadcaster.

• Cohen get Donation by followers.

• Another Service like Colo

Question 2

• Into which category or categories of e-

commerce do P2P file-sharing networks fall?

Anything of file that the vendors would like to sell

such as;

– Books

– CDs/DVDs

– Application

Question 3

– Pornographic Film/ Movie

– Piracy of Intellectual property

– Privacy/Cultural

– Change in Consumer Mind-Set & Behavior

– Change in business model/ business strategy– e.g. U2: Free music and revenue comes from concert and

others.

Question 3

• Is the record industry justified in attempting to shut them down? Why or why not?– Yes:

• P2P file-sharing protocols/programs lead to loss in revenue.

• For long term effect: Investors might not be interestedin this business.

• A disaster for artists (loss of income), consumers (loss of platforms the music industry COULD develop), and society (loss of jobs, artists).

• the proposed policy to disconnect file-sharers from the Internet; however, this couldn’t be done since the technology itself is legal

Question 3

• On the other hand, creativity and quality of work

might be improved to handle with the loss of income

crisis

Question 4

• Will the supreme court’s decision inhibit the development of P2P technology or the internet itself, as proponents of P2P services have claimed?

Not prohibited

- The concept behind file-sharing is totally legal

- But a the same time sharing copyrighted material is illegal

- Sharing file without the permission of the copyright holder is against the law

Question 5

• Why do people older than 21 tend to use

legitimate downloading sites whereas

younger people tend to use illegal sites?

– Income/ Credit cards issue

– Ethics/ Legal issue

– Kid/Teen Convenience Lifestyle (Youtube and MP3

file sharing)

Question 6

• What difference would it make if the existing

music labels disappeared for lack of revenue?

– No big company – Deficit/ bankruptcy

– Business will change business process.

• Cross functional business

• Targeting revenue from Brand Identity, Souvenir,

Performance ticket rather than selling the CDs

– Long tail artist e.g. Increase in Indy artists

Question 6

• What legitimate function do the music labels perform in the creation and distribution of original music?

– Sample music/Teaser w/o protection as a part of promotion tool and creating a “buzz” with no financial cost

– Targeting revenue from Brand Identity, Souvenir, Performance ticket rather than selling the CDs e.g.

U2: Free music and revenue comes from concert and

others.
