Oprah Winfrey has apologized for one of her tweets on Sunday which encouraged television viewers with Nielsen boxes to tune in to her network OWN ("Every 1 who can please turn to OWN especially if u have a Neilsen box").
She said in a statement to the New York Times:
"I removed the tweet at the request of Nielsen. I intended no harm and apologize for the reference."
A Nielsen spokesman added:
"It is Nielsen’s policy to note attempts to single out panel members to either change their viewing habits or otherwise influence or affect their reporting," the spokesman said later in an e-mail message.
Such attempts are rare, but are taken seriously by Nielsen, since its ratings are the foundation of the entire television industry, setting advertising rates and determining the success or failure of shows.
