New York: US President Donald Trump has possibly attracted more attention to a New York Times advertisement than he may have intended.

The news organisation will air its first TV ad in seven years during the Academy Awards on Sunday night, as the paper looks to highlight independent journalism amid Trump's attacks on the media as "fake news".

The Oscars is traditionally the most-watched non-sports event broadcast in the United States.

In a tweet to his 25.6 million followers on Sunday, Trump made sure everyone knew the ad is coming, potentially ensuring his own fans will hear the message.
