Ever since Steve Jobs announced that Flash will NEVER be allowed on the iPhone or iPad, there has been a lot of talk about HTML5 – how it is going to kill Flash once and for all. Let’s just ignore the fact that Apple, Adobe, Microsoft, and Google all have a large financial stake in the outcome of this argument. What about the technical feasibility of replacing Flash with HTML5? Well, HTML5 has some pretty cool features, but it is not going to kill Flash anytime soon. Here’s why:
Reason #1: The browser support isn’t there yet.
There is a lot of talk about how “all the modern browsers already support HTML5.” Well, that may be true, if you ignore Internet Explorer in your list of modern browsers. Somewhere between 30% and 50% of people on the web use Internet Explorer. At least 8% of people are still using IE6, which is a decade old and doesn’t even fully support HTML4! And what about all of the people using outdated versions of Firefox? The modern browsers may already support HTML5, but modern browser market penetration is probably somewhere around 50% and it will be years before it reaches a level necessary for most people to adopt it as the standard. As a developer, I can tell you that most developers will be stuck programming in HTML4 for the next 5 years or more, because it’s hard to explain to clients why their mother can’t look at their fancy new website. Flash has a 98% market penetration. HTML5 won’t be able to compete with that for a long time.
Reason #2: There is still no video standard for HTML5.
This is a related issue to Reason #1. There are currently at least 3 video standards competing for dominance in HTML5. Most browsers support only one of the 3 formats. It’s a bit like the recent Blu-ray vs. HD DVD war. Eventually, one will be the winner, but in the meantime, no standard means hassles for developers. It is simply easier for developers (and clients) to build things to a standard that most people can view, so most of them will probably stick with Flash video for now (remember the 98% market penetration from reason #1).
Reason#3: No DRM on HTML5 video.
HTML can deliver video directly through your browser with no plug-in. That’s great. The other great thing about HTML5 video is that you can right-click the video and save it to your desktop. Well, it’s great for consumers, but the idea of putting video on the web with no DRM (Digital Rights Management) makes studio execs panic. There is NO WAY that movie and TV studios are going to put all of their content out there to be downloaded and stored on your hard drive. Many large video sites like hulu.com have already said that they will not be switching over to HTML5 until the DRM issue is resolved.
Reason #4: Developers can’t protect their intellectual property.
As a developer, I can tell you that programming games and rich web applications isn’t easy. It takes hundreds of hours to program a cool Flash game. Even if I could do it in HTML5 and Javascript, I’m not going to to do it. The reason is simple: HTML5 code is visible to anyone who visits my web page. If I’ve spent all that time creating a cool game, I don’t want to expose all of my code to everyone in the world. If I did that, there would be crappy clones of my game popping up all over the web within a week or two. Flash allows me to protect my intellectual property in a way that HTML5 doesn’t.
Reason #5: Coding for multiple browsers is easier in Flash.
Not only does Flash protect my code from prying eyes, it provides me with a single set of rules to follow for coding across multiple platforms (Windows, Mac) and multiple browsers (IE, Firefox, Safari, Chrome, etc). To create something cool in HTML5, I would need to use Javascript. The simple fact is: Javascript sucks. It behaves differently in different browsers and you spend more time tracking down weird, browser-specific bugs than you do actually creating awesome web apps. Flash just makes development easier (and ultimately cheaper for clients).
Reason #5: HTML5 simply can’t compete with Flash in providing a rich media experience.
HTML5 has some animation capabilities built in to it, but Flash is way ahead of it in this regard. Flash provides a Graphical interface that a designer can use to create incredible animations and graphics. HTML5 requires a programmer to create cool animations. Flash is more powerful and easier for people to work with. I’m not saying that HTML5 and Javascript won’t catch up to Flash, but it won’t happen for a long time.
Reason #6: HTML5 is slower than Flash.
Ever since Apple’s announcement, people have assumed that what Steve Jobs said was true – Flash is too slow for the iPhone. Well, a number of clever people have actually run speed comparisons between Flash and HTML and have found that HTML5 is generally SLOWER and MORE RESOURCE INTENSIVE than Flash. Ouch. That doesn’t sound like progress to me.
Reason #7: Nobody really cares.
Frankly, most people don’t care how they get their content, as long as they get it. Despite what Steve Jobs thinks, no one really cares what technology is used to allow them to watch videos on YouTube. Even the Apple fankids who are applauding the decision not to put Flash on the iPhone probably don’t really care – most of them had never heard of HTML5 before this announcement and most of them still don’t really know what Jobs is talking about . It’s all about delivering the content. If Apple can’t give people the content they want, then people will use a different technology.
Obviously, I make my living as a Flash developer, so you may be inclined to think that I’m biased towards Flash. That may be true, but I am really just a developer – I will use whatever tools are best for the job. Right now, Flash is the best tool for creating a rich web experience . It has the best combination of capabilities and market penetration. HTML5 simply can’t compete with it right now.
