We all know it’s only a matter of time before Oprah takes over the whole world. And here’s the next step on her road to global domination: She’s swapping her eponymous website for what is now Discover Health Channel — soon to be rebranded as Oprah Winfrey Network (OWN).

Talk about underlining intentions.

There are limits to her power, for the time being:

The new channel will not initially carry “The Oprah Winfrey Show,” the top-rated syndicated daytime talk show featuring Ms. Winfrey as host. But Ms. Winfrey said that she had the option to end that show in 2010 or 2011 and could move the talk show to the new channel then.

“Eventually that will happen, we hope,” Ms. Winfrey said in a conference call with reporters on Tuesday.

The venture will be half owned by Discovery, of Silver Spring, Md., and half by Harpo Inc., Ms. Winfrey’s production company, which is based in Chicago. Ms. Winfrey will serve as chairwoman of the network, will have full editorial control over the joint venture and will be responsible for its “programming, branding and creative vision,” the companies said.

Oh, tell me this means Oprah’s going to buy the broadcasting rights to the National Hockey League! If so, I’ll be powerless to resist.
