Just days after Claire Danes and Julia Louis-Dreyfus took home “Best Actress” Emmys, Zimbio revealed their list of “2012’s Most Influential Women in TV”. Rising to the top of the list were Irish American stars Ellen DeGeneres and Mellissa McCarthy.

Ellen DeGeneres was crowned the social media queen with 13.4 million Twitter followers and 3.5 million Facebook fans. The headline for her Twitter homepage is “Laugh. Dance. Tweet." and it perfectly describes the joyful comedienne/talk show host's social media philosophy.

DeGeneres is a consistent, if not prolific, Tweeter who loves to post pictures and links to recent interviews, best wishes to her favorite celebs, and lighthearted quips like, "Where do I vote for Michelle Obama's arms?" Just like her daily talk show, Ellen's social media presence is refreshingly positive and not afraid to be a little bit (or a lot) silly.

Up top of actresses is Irish American funny woman, “Bridesmaid” star Melissa McCarthy. This “Mike & Molly” star is a mold-breaker who doesn't look like most women on TV and is proud of it.

The actress and mom worked her way up the ranks for years, appearing in lots of smaller roles before nabbing the role of Sookie St. James on “Gilmore Girls”. But it took a sitcom about a couple that meets at Overeaters Anonymous and a fearlessly funny turn in “Bridesmaids” to truly make McCarthy a star. A surprise Emmy and one Oscar nomination later, the actress is riding high and loving life.

Much more than a roundup of A-list actresses and Oprah, Zimbio has tuned into the social media mavens, stars under-30 and even some unexpected icons who currently wield the most impact on and off the small screen. From Kelly Ripa to Snooki and everyone in between, Zimbio ran the numbers, quantified the data, and tallied the tweets to determine the most powerful women in television in five key categories.
