Twitter on Saturday updated its app in Apple's App Store to begin charging $8 for sought-after blue check verification marks, in Elon Musk’s first major revision of the social media platform.

Axar.az reports that the change comes a week after Musk took over the social media company in a $44 billion deal. The billionaire entrepreneur and CEO of electric car maker Tesla (TSLA.O) cut half the staff at Twitter and has vowed to start charging users more.

In an update to Apple iOS devices, Twitter said those who "sign up now" for $7.99 a month can receive the blue checkmark next to their user names, "just like the celebrities, companies and politicians you already follow."

Before Musk took over, blue check marks next to a person's user name meant Twitter confirmed the account belonged to the person or company claiming it. It was not immediately clear how or if Twitter planned to verify the identity of the user beyond charging a fee.

According to the iOS notification, other benefits in the update include "half the ads", the ability to post longer videos to Twitter and priority ranking for quality content.

Twitter and Musk, via Tesla, did not immediately respond to a request for comment.
