March 13 is the day when YouTube will stop working for people still living in the stone age and running IE6. The announcement comes at a time when a significant amount of companies with a Web presence are desperate to see IE6 disappear forever.
As you can see in the screenshot above, YouTube will have an interstitial appear when users on older browser try to watch a video on YouTube. Google says the interstitial will show up indefinitely every two weeks until the user upgrades to the most recent version of their browser. Google deems anything below IE7, Firefox 3.0, Chrome 4.0, and Safari 3.0 as an “older browser.” Users on these browsers will still be able to watch YouTube videos, but additional features that Google plans to roll out may not be supported in these older browsers.
