Twitter's US advertising revenue plunged 59 percent year-over-year during a recent five-week period, The New York Times reported today. The firm's US ad "revenue for the five weeks from April 1 to the first week of May was $88 million, down 59 percent from a year earlier, according to an internal presentation obtained by The New York Times."

Owner Elon Musk said in an April BBC interview that "I think almost all advertisers have come back or said they are going to come back." But internal projections are grim, according to the NYT report. One internal forecast cited by the NYT predicted that Twitter's US ad revenue in June "will be down at least 56 percent each week compared with a year ago."
