Oprah Winfrey has launched her own TV network, which will offer round-the-clock lifestyle programmes.
The channel is called the Oprah Winfrey Network (OWN). It is a joint venture with the Discovery channels.
The BBC reports the start date has been delayed twice and its cost has reportedly swollen to $US189 million.
Oprah, 56, appeared on a preview programme to launch the network on Saturday.
The US talk-show host has built up a huge fan base during 25 years as host of the syndicated Oprah Winfrey Show.
The programmes on the new channel have a focus on empowerment, improvement and positivity aimed mainly at women, her core audience.
Among the programmes scheduled is a reality show starring the Duchess of York, Sarah Ferguson, and Why Not?, hosted by Canadian country singer Shania Twain.
