Oprah will announce Friday to a live television audience that she will end her talk show career.

James Hibberd posted the letter on his website that was sent out to vendors and partners of the show regarding her departure. Read it after the jump alongside with CBS’s response.

Oprah, we love you!!!

The show will make its last airing on September 9, 2011 after being on air for 25 years. What does this mean for daytime television?

Dear Friends:
Over the past several weeks, my team and I have had conversations with many of you to help address your questions about the future of “The Oprah Winfrey Show.” Of course, the one question we couldn’t answer was the one that only Oprah could. And tomorrow, she will do just that.

But before she speaks to her loyal viewers, we wanted to share her decision first with you – our valued partners for more than two decades.

Tomorrow, Oprah will announce live on “The Oprah Winfrey Show” that she has decided to end what is arguably one of the most popular, influential and enduring programs in television history. The sun will set on the “Oprah” show as its 25th season draws to a close on September 9, 2011.

We welcome you to share this news this evening with your colleagues and viewers. As we all know, Oprah’s personal comments about this on tomorrow’s live show will mark an historic television moment that we will all be talking about for years to come.
We want to thank you for the partnership and friendship we have shared over the years. Your invaluable support has helped us to create the phenomenon of the “Oprah Show” that we’ve all been so proud to be a part of for the last 24 years. My staff and I will be calling all of you directly tonight and tomorrow. We look forward to speaking with you.

And, if you think the last quarter century has been something, then “don’t touch that dial” as together we plan to make history in the next 20 months…and beyond.

CBS, the company that distributes her show responded back with:

We have the greatest respect for Oprah and wish her nothing but the best in her future endeavors. We know that anything she turns her hand to will be a great success. We look forward to working with her for the next several years, and hopefully afterwards as well.
