The Oscars will again go without a host next month, repeating a format credited with boosting ratings in 2019, US network ABC confirmed Wednesday.

"Together with the Academy, we have decided there will be no traditional host, repeating for us what worked last year," ABC President Karey Burke told a television summit near Los Angeles, according to showbiz website Deadline Hollywood.

"[It will have] huge entertainment values, big musical numbers, comedy and star power."

In 2019, the Oscars decided to go without a host - the first time in three decades - after their original choice Kevin Hart pulled out when old homophobic tweets of his resurfaced.

In the end the event was considered a success and the show enjoyed a year-on-year increase in ratings.
