The Galaxy Note 7, Samsung's flagship handset, has been recalled because they're exploding or catching fire.
The disaster could cost the company more than $20 billion.
But Samsung's not the first to get hit with a tech catastrophe.
Just a few years ago Blackberrys were the must-have in the world of business.

The failure cost $76 million, as well as countless customers who switched to Apple or Android products.
A few years earlier, Microsoft updated its popular Windows XP to Windows Vista.

MySpace redefined what the word "friend" meant, but the pioneer of social media went from hero to zero.
News Corp bought the site in 2005 for $822 million.

In 2010 Barack Obama passed the Affordable Care Act, allowing Americans to sign up for health insurance online.
But Obamacare's rollout three years later was a disaster.
Some estimates suggest only 1 percent of those trying to sign up in the first week managed to do so.
The errors were blamed on high traffic volume and a number of design issues.
