The 'Oprah effect:' Does everything she touches turn to gold?

Wall Street was all aflutter Monday about "the Oprah effect."

She bought 10% of Weight Watchers and the company's stock soared. Big news.

But anyone who follows pop culture has watched Oprah's turn-to-gold touch for decades — on books and magazines, movies and television, fashion and lifestyle products, on politics and political causes, and on making stars out of nobodies she has embraced.

Ever heard of psychologist Dr. Phil and health-expert Dr. Oz before Oprah reached out and touched them? Alternative-medicine advocate Deepak Chopra and financial adviser Suze Orman? Lifestyle designer Nate Berkus?

They're all celebrities now, after years of appearances on Oprah's daytime talk show led to their own TV shows.
