Some users may have already seen a message from Instagram with a head’s up that advertisements will soon be displayed in their streams.
It was about a year ago that Instagram started sprinkling ads into user streams in the U.S., and a similar move was made in the U.K. in September.
In November 2013, Instagram introduced ads in the U.S. with the fashion brand Michael Kors purchasing the first Instagram campaign.
Instagram, which was acquired by Facebook in April 2012 in a US$1 billion deal, said it has 200 million users worldwide.
The company said it has shared more than 20 billion photos to date and averages about 60 million daily.
