Part 3: Why Has Adobe Withdrawn Its Support for FLV File Format

FLV file format got its recognition in the late 90s, and soon many platforms used this format for streaming videos like YouTube, including Facebook and other sites.

However, it got replaced with HTML5 format, and eventually, many platforms, including Adobe, eliminated Flash Player, which resulted in the downfall of the FLV format.

The major cause behind the elimination of Flash files was the security risk, as hackers could easily steal the data from such files.

With the inception of the HTML5 format, online sites and platforms got various benefits through it. For instance, HTML5 can easily function in every browser and does not demand external plugins. Also, it provides great security and offers a good processing speed, unlike the FLV format.

Another major reason that worked as a catalyst behind the Flash Player was the invention of the first iPhone in 2007. Apple never showed compatibility with the Flash Player from the start causing many platforms to discard the FLV file format.

Here are some historical details of the famous platforms discarding Flash content:

  • 2011: In this year, Adobe started to emphasize the HTML5 format for mobile devices.
  • 2015: As Flash player consumes a larger amount of battery power, Chrome decided to discontinue the Flash content to save more power for laptops and other devices.
  • 2017: Facebook also opted for HTML5 this year for their game content.
  • 2019: Firefox also started abandoning Flash, causing a major downfall for the FLV files.
  • 2020: Microsoft initially tried to run Flash content but eventually discarded Flash content from Internet Explorer and the Edge. Moreover, Adobe eventually withdrew its support from the Flash Player and eradicated all the related content from its website on 31st December 2020.
