One of the changes that the company has been discussing since Musk took over is the introduction of a verification check mark on the profiles of users.
The announcement was included in the notes that accompanied the new update to the account. The paid verification system was a new feature of the website.
The announcement promised power to the people. Just like celebrities, companies, and politicians, your account will have a blue checkmark.
The company has more than $1 billion a year in interest payments and is loaded with $13 billion in debt. Pressure has been put on to cut costs and raise revenue. Roughly half of the company's work force was laid off.
In addition to charging for verification, Mr. Musk and his advisers have been considering a number of other ideas to bring in more revenue.
Half the ads and much better ones will be included in the update notes that were unveiled on Saturday.
In a series of messages on Saturday, Mr. Musk said that the company was working on an update that would give users the ability to attach long-form text to a message.
The change to the signature verification system has caused a lot of controversy. The company used to assign a blue circle with a white check mark to high-profile figures. Some election-integrity advocates are worried that the new paid verification system could make it easier for bad actors to impersonate politicians.
The update notes didn't mention any steps that could be taken to prevent impersonation. On Saturday, Mr. Musk said that the company would keep their money. He said that if a scam artist wanted to do this a million times, they would need a lot of money.
