Twitter is looking at introducing advertisements among the short messages that users see in the most active part of the social networking service, according to people with direct knowledge of its plans.
The move to place “promoted tweets” in the main “stream” of tweets on the service is likely to be controversial with users who have seen only limited and unobtrusive marketing messages so far in Twitter’s five-year history.
Other commercial options under discussion include deals and offers similar in style to rival Groupon, which aggregates consumer demand for time-limited specific offers. It is also looking at introducing enhanced profile pages for brands and media management tools, which could allow advertisers to pre-schedule 140-character posts.
