Oprah Winfrey apologizes for tweet

London: International talk show queen Oprah Winfrey has issued an apology for breaking TV ratings rules and urging fans to watch her Oprah's Next Chapter show instead of the Grammy Awards, according to reports.

Oprah invited followers to turn off music's big night and switch to her network, OWN, on Twitter.

"Everyone who can please turn to OWN, especially if u have a Nielsen box (sic). Commercial Grammy people..you can turn to Own," she tweeted.

But ratings compilers at Nielsen demanded Winfrey to remove her tweet and her posts were later removed. "I removed the tweet at the request of Nielsen. I intended no harm and apologise," Winfrey said in a statement.
