Oprah Winfrey earns $12.5M after single tweet

CHICAGO, Jan. 27 (UPI) -- Entertainment mogul Oprah Winfrey earned about $12.5 million after posting a single tweet promoting Weight Watchers Tuesday.

Market reports say Weight Watchers shares increased 19 percent within an hour after Winfrey tweeted about eating bread every day and losing 26 pounds on the program.

"Eat bread. Lose Weight. Whaaatttt?" Winfrey, who reportedly owns 6.4 million shares -- about 10 percent -- of the company, tweeted alongside a promotional video in which she explains the joy of being able to eat what she likes on the Weight Watchers program.

In total, USA Today reports the OWN network creator earned $19.2 million over the course of the day following her timely tweet. Winfrey first invested in the company last year, making $70 million in 24 hours following the announcement.
