Instead, Chrome will use by default HTML5, a more modern standard that can save battery life on laptops.

Google posted this on its Chrome blog:

"Today, more than 90 per cent of Flash on the web loads behind the scenes to support things like page analytics. This kind of Flash slows you down, and starting this September, Chrome 53 will begin to block it. HTML5 is much lighter and faster, and publishers are switching over to speed up page loading and save you more battery life. You'll see an improvement in responsiveness and efficiency for many sites."

If a site supports only Flash, then Google says that users will have an option to enable Flash when they first visit the website.

In the early days of the internet, Flash was one of the few ways to build rich experiences on the web — so it was commonly used for videos, games, or even interactive navigation.

But Apple decided not to support Flash on the first iPhone, starting its long downfall as a web standard, and then CEO Jobs gave the company's reasons for, in his words, "leaving the past behind."

According to Jobs in 2010, there were six reasons why Apple chose not to support Flash on the iPhone:

1.Adobe Flash is proprietary.
2.Newer video formats are superior and widely available.
3.Flash is insecure and does not perform well.
4.Flash kills battery life.
5.Flash does not support touch.
6.Apple did not want developers writing Flash apps instead of iPhone apps.

For years, Google has signaled that it agrees that Flash is an antiquated format that must die, and now it looks like it's finishing the job.
