After 25 years on television, Oprah Winfrey will leave her popular hour-long daily daytime talk show to go 24/7 on January 1, 2011, with her channel called OWN: the Oprah Winfrey Network and featuring a prime-time show called 'Oprah's Next Chapter'.

In partnership with Discovery Communications, the OWN channel is set to debut at noon on the first day of the new year in 80 million homes, replacing the Discovery Health Channel on cable and satellite.

Programs will be hosted by well-known experts and celebrities, such as Sarah, Duchess of York on a show titled Finding Sarah, pop-country singer Shania Twain hosts Why Not? With Shania Twain, and comedian Rosie

O' Donnell returns to television.

Master Class features stars such as music impresarios Jay-Z and Simon Cowell, actor Sidney Poitier, poet Dr. Maya Angelou, and Dr. Condoleezza Rice sharing their stories of successes and failures.

Excellent Adventure is produced by actor Ashton Kutcher's company and Your Own Show is a contest for viewers who audition to get their own television show on OWN. Reality-based shows include Breaking Down the Bars: a docu-reality series following the transformation of female prisoners working with a therapist on rehabiliation.

Reflecting Oprah's philosophy of television "for people who are all interested in reaching their greatest potential," her All-Stars show delves into questions on health, wealth, and well-being. There are shows like Visionaries: Inside the Creative Mind as well as series on parenting and sex advice.

In Canada, the Viva channel will be rebranded as OWN on March 1, showing select shows from the network in January and February.
