Apple CEO Steve Jobs made, what some might consider, a risky decision by excluding Flash from the iPhone and iPad in favor of HTML5, but significant growth rates of the standard shows he was on the right track.

[ad#Google Adsense 300×250 in story]According to MeFeedia, 10 percent of all video on the Web was HTML5 compatible in January 2010. That grew to 26 percent in May, right around the time the iPad was released.

With its most recent numbers, MeFeedia says that now 54 percent of web video is now compatible with HTML5. That’s growth of more than five times since the start of the years.

The company notes that Flash is still the dominant player for desktops, but mobile devices are driving HTML5 growth. That would be the iPhone, iPad and some Android devices, as well.

MeFeedia’s index includes over 33,000 publishers including Hulu, CBS, ABC, YouTube, Vimeo, DailyMotion and others.
