It also has its share of problems, though. Development time takes longer; it takes forever to download Flash-based content on a slower network (which in turn requires the development of a Flash preloader); a knowledge of ActionScript is required to really unlock its full potential; it presents an inconsistent and incompatible mobile experience; it’s SEO hit-or-miss; and Flash players are usually buggy, crash regularly, require frequent updates and create a host of security and privacy issues.
Until recently, Flash has pretty much been the only game in town with regards to the creation and handling of the kind of content it supports.But HTML5 has pretty much won the fight for the future of Web browsing. Not only has the new syntax proven to be very multimedia friendly, thus eliminating the need to develop and/or implement Flash- based technology, Adobe itself has publicly encouraged designers and developers to pursue HTML5 solutions – at least when developing for mobile Web.
Flash will still be critical part of the desktop multimedia experience, however, especially since only the latest versions of most browsers can read HTML5. Even if Flash is on the path towards becoming an outdated Web technology, too many desktop browser users have come to expect and rely on it to display interesting and innovative forms of content.
And they’ll be expecting it for the foreseeable future. It’s going to take awhile for HTML5-friendly browsers to become standard-use across the Web, so the Flash phase-out isn’t likely to happen as quickly as some would expect (or want). Designers and developers have been creating tailored Web experiences for different platforms for the past few years, and while it isn’t an efficient or productive way of doing things, it’s more or less how things are going to have to be until a universal, cross-device standard is implemented.
So, while the future may belong to HTML5, Flash is still an appropriate technology in certain cases for present Web development.
