Reality TV isn't just putting television writers out of work. It's also helping to raise unemployment at the Screen Actors Guild.

KIm Kardashian (of 'Keeping Up With the Kardashians') will be starring as a bad girl (with TV hostess Vanessa Minnillo) on an upcoming episode of 'CSI: NY.' Meanwhile, two stars of Bravo's 'Real Housewives of New Jersey,' Teresa Giudice and Jacqueline Laurita, will play themselves on an episode of NBC's Jersey-set medical drama 'Mercy.'

Here are seven people who used their reality TV notoriety to their advantage. They have found success in other TV genres, film, or entrepreneurial pursuits. Some just found more fame in the genre that put them on thee map.

7. Colleen Haskell (Survivor): Colleen was in the first season of Survivor (Borneo) and while she didn't outwit, outplay and outlast the other cast members, she did make a good run of her fifteen minutes. She finished sixth in her season but was such a genuine and fair player that when her torch was extinguished Richard Hatch called her a "wonderful person." Using her American-apple-pie-pretty-girl-next-door appearance and attitude, she parlayed her reality TV fame into more roles in both television and film. She did a Blistex commercial and had a guest spot on That 70's Show. Most notably, however, she starred alongside Rob Schneider in The Animal (2001). Pretty good for a Catholic school girl from a small town in Maryland.
