Don't Change Horses Mid-stream

Second Economic Report:

After consulting with Justin, Hayley, and Marion, I feel that Apple switching to the BitTorrent distribution system is currently not an economically sound investment.

With Bit Torrent, Inc.’s new Entertainment Network just being released, initial reports on the effectiveness of the network to distribute protected multimedia are shaky. A report on the system by “Ars Technica” showed many early flaws in the Bit Torrent Entertainment Network. According to the report, many of the problems found by the user were the result of Bit Torrent’s increased focus on legality. This caused two blocked attempts from the user to purchase movies, saying she was in a country that was not permitted to use the system. But the user’s billing address and computer location were registered in Chicago, IL. Next there were problems with the compatibility issues of DRM between Mac and PC users. This would be a problem that Apple would have to research and develop a new system of DRM that could be costly R&D. Upon the final successful completion of a download, when attempting to view the movie, the user was met with a prompt that declared “the media usage rights for the file are not valid.” Also, the download of the popular new release, “Nacho Libre,” took 47 minutes to complete. In Justin’s trial download from iTunes, “The Hunt for Red October” too barely 9 minutes.

This trial of Bit Torrent’s attempt to legally distribute licensed media raises many economic concerns if Apple were make the same attempt. Many encrypted bits of data from many different users would could cause problems (such as in the report) that may affect the user’s viewing experience. A recent study of the iTunes Music Store shows its growing popularity among internet users. In November 2006 alone, the Music Store attracted 20.8 million new users. This is reflected in iTunes revenue in the first three quarters of 2006 being up 84% from the first three quarters of 2005. And iTunes’ popularity continues to soar. Initiating a new unproven system in the hopes of delivering HD DVD movies more quickly is inherently risky. But the risk is even greater given iTunes’ success and popularity. If users have a frustrating experience like the trial of Bit Torrent’s system, Apple could be at a huge risk of alienating its loyal consumer base.
Consumer confidence and familiarity are certainly not to be overlooked. iTunes currently has a simple, artistic, and enjoyable interface that has attracted many customers. I feel Apple must take a risk-averse approach to completely altering its downloading format.

The need for alteration of downloading format is in fact very questionable. iTunes users have come to rely on paying for a download and receiving their movie order in a short time, in many times shorter than BitTorrent. BitTorrent’s own Vice President stating, “the download time [of BTEN] is analogous to downloading from [Apple's] iTunes.”
Many users enjoy the ability to begin a movie download and begin viewing it as the download is in progress. Essentially, this could cut the waiting download time down to just a couple of minutes. This is unfeasible under the BitTorrent system where separate pieces of data arrive in random order and must be pieced together upon completion of the download. Apple’s current system is arguably faster, more reliable, and more assuring then BitTorrent. When a user downloads from iTunes, he knows he is receiving his movie directly from a reliable and reputable Apple Server. Many concerns can be raised when consumers are forced to start downloading from other unknown users that could be potentially harmful.

Apple already holds a strong share of the online movie download market. Mac users are locked in to using iTunes as a downloading platform, and PC users are given the option—which many choose to accept. Coupled with this is the incredible importance of the video iPod. “total iPod sales reached 88,701,000 units as of January 2007.” Users hoping to download movies must use iTunes and Apple’s DRM to play on their iPod. This gives Apple a quasi-monopoly on a fairly sizeable consumer base of iPod users and Mac loyalists. There does not seem to be a need to change their current pricing strategy of $14.99 for new releases and $9.99 for all other movies. This standard pricing strategy (modeled on the $.99 per song Music Store pricing) has been one of Apple’s greatest causes of success.

Since nearly 48% of Apple’s profits are a result of iPod sales, I would advise them to spend investment funds on developing a new piece of hardware through which to play movies downloaded from iTunes. Although the video iPod is an option, some type of small portable device with a larger display more geared toward viewing would result in greater sales from users forced to download from iTunes. It is smarter to force consumers to purchase movies from iTunes after they buy their hardware than to try to attract them by “hopeful” better download times after investing in a new BitTorrent system.

Finally, the HD-DVD/Blu-Ray market has yet to be proven a wild success. Not all new releases are even formatted to this new standard. Yet, if they do prove to be successful, Apple may have to dedicate more hardware and bandwidth to its iTunes infrastructure to ensure reliable downloads. But this investment would be less risky (Apple would simply be expanding what it has already found success) than applying funds into a BitTorrent experiment that could have high detrimental effects on Apple’s role in the future of online movie downloads.

Apple and BitTorrent: A Disaster Waiting to Happen…

As the market for HD-DVDs is on the rise, Apple must come up with an efficient means of distributing content to their end users. Although many different techniques are under investigation, BitTorrent has become one of the preferred methods. Currently, any iTunes user can log in to their account to access the wealth of data stored on Apple’s servers available for download. By implementing a BitTorrent style system, Apple would be essentially redesigning their existing system by storing small bits and pieces of files on their user’s computers. After researching BitTorrent in detail and carrying out various experiments, I believe that Apple should continue to offer their iTunes store without incorporating BitTorrent technology.
Apple’s FairPlay DRM is one of the main reasons why BitTorrent is an unfeasible solution to distribute HD distribution. Apple encrypts the video content available from within the iTunes store as protected MPEG-4 files, which require a user key to decrypt. When a user makes a purchase at the iTunes store, they are essentially using their own unique key to scramble a file that contains a master key. Only the user with access to this key can unscramble the file afterwards. Because the way Apple implements encryption, it is impossible to use BitTorrent to access content that has been encrypted by a wide variety of different user keys. Due to the fact that BitTorrent downloads small portions from all nearby users, if someone were to download a chunk of data from each uniquely scrambled file, they would end up having unplayable content. Because distributing unencrypted HD media is not an option, in order to make use of BitTorrent, Apple would have to come up with a new means of encryption so that all portions of the file work together.
The lack of simplicity is yet another reason why BitTorrent is not a suitable replacement. Users who choose the iTunes Store have certain expectations and desire a straightforward experience. Most torrent applications do not incorporate a dynamic hash table, thus users are forced to locate and download the torrent they desire to supply the application with the relevant metadata, tracker, etc... This procedure does not embrace simplicity, and has the potential to turn many customers away from using Apple’s product to download HD content.
Constant performance is also lacking on BitTorrent overlaying networks. Even though popular torrents download at high rates because of large swarms of users storing and sharing bits of content, as the torrents get older, swarms disappear and seeds have fewer reason to continue offering their complete version to the rest of the community. The result is that it takes a shockingly long time to download older and less popular media using BitTorrent. While users of the Apple iTunes Store might never reach the download rate peaks BitTorrent users experience, they don’t suffer from the extremely slow rates exhibited when only one person is a seed. Customers expect constant performance for all types of media. I did a side-by-side comparison to determine whether or not BitTorrent allowed me to download “The Hunt for Red October” any faster than the traditional iTunes Store. I was shocked to discover that my 1.46GB download from Apple’s iTune Store took merely 9 minutes, and even more amazed to see that my BitTorrent client informed me that I had 17 hours remaining. Even though “The Hunt for Red October” is an older movie released in 1990, the fact that my BitTorrent client was only able to connect to 7 seeds is unacceptable. On top of that, I was able to watch my video from iTunes while it was in the process of downloading, something that is impossible in BitTorrent due to bits and pieces arriving out of order.
BitTorrent also violates people’s privacy by forcing users to allow uploads in order to enjoy high download rates. People who purchase content from Apple have the right to keep their transaction confidential. However, BitTorrent would attempt to download private content from nearby seeds without first seeking their approval. Apple iTunes already offers adult-oriented material, and as adult oriented HD-DVDs become increasingly popular, people may not want to disclose to nearby nodes their entire library. These individuals would appear to be “free-riders” and thus would be punished for not sharing their media. In a BitTorrent system, someone who attempted to download pornographic content could see all of the nearby seeds that have already purchased it due to the way IP addresses are disclosed. This could lead to very embarrassing situations and privacy violations, which could result in potential lawsuits.
While BitTorrent does provide its users with many benefits, Apple’s conventional method of distributing media content to purchasers seems to work very well. While a single layer HD-DVD is capable of storing up to 15GB of content, Apple must dedicate more hardware and bandwidth to their core servers in order to ensure that their customers can enjoy fast download speeds. Requiring users to rely on a BitTorrent client adds complexity and is counter productive to Apple’s end goal of being the number one HD-DVD distributor.
