Twitter has told marketers they can now place video ads near the top of people's timeline feeds.
It says the First View feature will give their clips "premium placement" on users' devices. It is initially being rolled out to the US ahead of a global launch.
The announcement comes on the eve of the company's latest financial results.
One expert said the move might help boost Twitter's profits in the short-term but was likely to backfire.
"The
reason why Facebook has been so successful of late is that it has been
able to put sponsored posts and videos into people's feeds," commented
Richard Holway, chairman of the TechMarketView consultancy.
