Twitter Inc is now considering if it should add a premium version to the popular tweet interface aimed at professionals, said the company on Thursday. That raised the possibility it could collect fees for subscriptions from some of its users for just the first time since its launch.

Like most of the other companies in social media, Twitter since being founded over 11 years ago has placed its focus on building a larger user base for its free service with advertising supporting it. In February, Twitter posted that it had over 319 million users across the globe.

However, unlike Facebook, the much larger social media giant, Twitter had not been able to attract enough advertising revenue to have a profit even though its popularity with United President Donald Trump and other well-known celebrities puts it at the center of worldwide attention.

New subscription fees might come from Tweetdeck an already existing interface that aids users in navigating through Twitter.

Currently Twitter is carrying out a survey that is assessing the interest in a more enhanced, new version of Tweetdeck, said a company spokesperson on Thursday.

The spokesperson added that the company regularly conducts research to get feedback about the Twitter experience of users and to inform the company better on its product investment decisions.

She added that the company continued exploring new ways that Tweetdeck could become more valuable to professionals.

There has been no indication Twitter was going to consider charging all users fees.

Word about this survey had leaked earlier on the microblogging site when a New York Times affiliated journalist posted on the site screenshots of what a Tweetdeck premium version might look like.

The new premium version could include tools that have more power to help journalists, professionals, marketers and others in the community to find out what is going on in our world at a quicker rate according to a screenshot posted on an account.

The description added that the new experience could end up being ad free.

Other companies in social media like LinkedIn owned by Microsoft, already have memberships on a tiered basis with versions that require subscriptions offering more access as well as more data.

During the final quarter of 2016, Twitter suffered through its slowest growth in revenue since going public over four years ago, and revenue generated through advertising dropped during the same quarter.
