The Washington Post reports that NBC’s “Today” show tech editor Corey Greenberg has admitted to accepting payments from Apple, Sony, HP and other companies, charging $15,000 each to promote their products on local news shows. Greenberg appeared last July on the “Today” show to praise Apple’s iPod as “a great portable musical player… the coolest-looking one” and said “this is the way to go.” He has also appeared several times on CNBC talking up Apple’s products. “I have never accepted payment to place a product on NBC News,” Greenberg said, however. “I have never accepted payment to say nice things about a product in any venue.” He said companies hired him as “a spokesperson who could talk credibly and understandably about consumer products,” but that he would no longer accept payment for appearances on local shows.
