Twitter has reported its first Quarterly Net profit helped by a rise in video advertising sales.
The news gave a massive boost to Twitter's shares which closed 12% up on the day.
That was despite the number of people using the social network coming in below expectations.
Twitter's previous failure to make a profit had confounded investors given its widespread use and popularity among celebrities and politicians.
Net profit was $91.1m (£65m) in the fourth quarter of 2017, compared with a loss of $167.1m for the same period a year ago.
Twitter, which has posted consistent losses since it became a public company in 2013, said it expected to be profitable for the full year of 2018 as well.
