Micro-blogging service Twitter is thought to be preparing to serve adverts to its users.
According to story on the Wall Street Journal's AllThingsD website, the ads will be linked to Twitter searches. For example a search for 'laptop' may generate an ad from Dell.
AllThingsD also said the 140 characters or less adverts will only be shown in search results, or add-on services such as TweetDeck that have agreed with Twitter to display the ads.
"Everyone I've talked to cautions that the plans are evolving and that there are plenty of details to work out," said Peter Kafka on the AllThingsDsite.
However, Twitter has yet to reveal pricing and a launch date.
Twitter engineer Alex Payne added to the speculation when he revealed that the Micro-blogging service is set to get some new features.
"If you had some of the nifty site features that we Twitter employees have, you might not want to use a desktop client. (You will soon)," he said in a tweet, which has since been removed.
Payne then added that the "web client team is building cool stuff. It's going to inspire desktop app developers. Same data, new perspectives".
