This has been in the works for months now, but the final day of support has finally been discovered by Ars Technica. Google has announced through on it’s YouTube support page that they will be ending Internet Explorer 6 support on March 13. The decision is simple, Google can’t keep holding back new features just because they won’t work on older browsers.

If you happen to be one of the unfortunate IE6 users who forgets to upgrade, YouTube will begin warning users by using an interstitial when you try to view a video using an out of date web browser. The message will also recommended five browsers supported by YouTube. The new minimum requirements will be the following: Internet Explorer 7, Firefox 3.0, Chrome 4.0, and Safari 3.0. Anything older than those will be deemed as an older browser and recommend that you upgrade to the latest version.

YouTube isn’t the only Google product that is dropping support for older browsers. It has previously been announced that they will be ending support for Google Docs and Google Sites on March 1, 2010. There are also plans to do the same for Google Mail and Google Calendar by the end of this year.

The end of support for these products seems to affect Internet Explorer 6 users the most. They might still function in Internet Explorer 6, but clearly the end is finally near for the old browser. Microsoft has been promoting Internet Explorer 8 for some time now, trying to get users to upgrade. It seems to have helped reduce the amount of IE6 users, but there are still a large number of users worldwide. Microsoft will continue to support IE6 until 2014, but you can be certain most internet sites will be dropping support long before that date as long as companies like Google are leading the way.
