Oprah may be gone, but the concept still works. You can replace Oprah with any number of TV talk shows.
The trick to making this work well is to pick the guests or topics that are not already headliners. For example, if you know Sean Hannity is going to have Mit Romney on his show, you probably won't get any traction out of that...
BUT, if you know that Good Morning America is doing a piece on Mary Putinhegimer, a local baker that makes cakes in the shapes of presidential candidates... that would be a winner!
This works great on WordPress blogs with the relevant keyword tags. If your site is a Google News site, even better.
One last thing, just reading this post won't increase your traffic. You actually have to do something!
