In light of recent announcements from both Safari and Chrome that they’ll stop advertising Flash Player’s presence I’ve decided to see how ready the Internet is to move past Flash’s legacy and into an HTML only era.

I’ve configured Chrome to ask me before running any Flash content (Preferences… > Content Settings… > Plug-ins).  This made it easy to identify Flash content on pages since with this change Chrome overlays Flash content with a big grey puzzle icon.

In a second run I’ve disabled Flash entirely from chrome://plugins/ to see if the website offers any – HTML based – fallback experience.

Disabling Flash Player showed me just how much Flash content there is out there.

Some of the (big) websites I’ve identified that use Flash content had HTML5 alternatives (Twitch, Speedtest, Yahoo, Amazon, etc.) but some did not (Namely Hulu, Pandora, Napster, Spotify, NBC, CBS and YouTube’s video editor) and some only offered limited functionality (Google Finance’s stock charts).

YouTube

YouTube Video Editor‘s Enhancements, Audio & Annotations sections refused to work without Flash and there is no HTML version.

YouTube's Video editor uses Flash

Some rare DRM protected videos also refused to playDRM'ed YouTube videos use Flash

And disabling Flash Player entirely produced no HTML alternative for them

DRM'ed YouTube videos have no HTML fallback yet

Twitch.tv

Even though they do have an HTML version Twitch.tv still prefers to use Flash for their live streams because the HTML version doesn’t yet support ads. For now The HTML version is used mostly for paid Twitch Turbo subscribers.

Hulu

Hulu is another service that’s making heavy use of FlashHulu's video library is entirely shown in Flash

No HTML version either, with the site asking me to download Flash Player when it was disabled.

Hulu doesn't yet have any HTML based fallback

South Park Studios’ full episodes library is are also powered by Hulu

South Park's video library is Flash based

OOKLA

Both Ookla’s Speedtest.net & Pingtest.net make heavy use of Flash:

Ookla used Flash for a long time to measure one's Internet speed

Pingtest uses Flash technology to measure your ping response times

But I was able to test my speed because an HTML only beta version is available for Speedtest. No such version is available for Pingtest though.

Amazon

Amazon’s video reviews default to FlashAmazon's video reviews default to Flash

But viewing them with Flash Player disabled did not prove difficult as they do have an HTML fallback. Here’s Adam’s review of the great Logitech C920 webcam:

Amazon.com HTML video player for video reviews

Rick and Morty

Adult Swim’s publicly available, on demand, Rick and Morty episodes also default to Flash:Adult Swims video library works on both HTML only and Flash enabled browsers

Disabling Flash Player brought up their HTML player but it refused to play any episodes. Their live 24/7  Rick and Morty stream did work correctly though with Flash disabled.

NBC

Watching an episode of Running Wild with Bear Grylls on nbc.com proved difficult. NBC was very adamant about needing Flash Player for their video content.NBC is very adamant about needing Flash Player for their video content

Not surprisingly given their video player takes the whole pageNBC's video player is huge

CBS

CBS’s video library is in the same situation. Here’s trying to watch CSI: Miami with Flash Player disabled:

CBS' video library requires Flash Player

Configuring Chrome to ask me before running Flash content quickly brought out the Flash content on the page:

CBS' video library requires Flash Player

Google Docs/Sheets/Slides

Google’s Docs, Sheets & Slides suite has a nice little feature where you can add  an image to a document (or spreadsheet or slide) by taking a webcam screenshot. It doesn’t work without Flash:

Google Finance

Viewing and playing with interactive charts of AAPL stock is not possible without Adobe Flash Player:

Only static charts are shown when Flash Player is disabled:Static charts are shown on Google Finance without Flash Player

PC World

PC World‘s homepage video playlist immediately jumped to the grey puzzle icon.

But individual videos did play properly in their videos section:

Napster

Napster did a great job of notifying me about Flash Player missing while still allowing me to browse the library. It has a script in place detecting both when Flash Player is disabled AND when it’s just prevented from running (Chrome setting). The same message was shown to me in both situations:

It looks like you’re missing the Flash player, or your Flash plug-in is disabled. Napster requires the Flash player for audio streaming. Get Flash.

No HTML alternative exists for Napster when Flash Player is disabled

No HTML alternative exists for when Flash Player is disabled.

Pandora

Pandora is the most adamant about needing Flash Player with the site not allowing you to sign in or browse their artists without Flash Player.

No HTML alternative.

Spotify

Spotify’s Web Player (https://play.spotify.com) did not start either

Spotify's web player needs Flash player as well.

No HTML alternative.

Yahoo

Yahoo’s coverage of the VMA’s played correctly without Flash

But it does default to the Flash video player if Flash Player is present
