Tina Sharkey (b. 1964) is an American entrepreneur. She co-founded iVillage, led multiple businesses at AOL, and started the digital internet division at Sesame Street. She is considered one of the pioneers in the evolution of new media, from the introduction of HDTV to the mass-market adoption of the Web, social networking and mobile computing platforms.

Sharkey was born in New York City. Her father and grandfather worked in the garment industry, as did her mother, Mona Sherman, who became the president of Perry Ellis America when Sharkey was in high school. She attended the University of Pennsylvania, spending a semester at the University of Paris: Sorbonne, and earned a Bachelor of Arts in International Relations.

Sharkey began her career as part of the team that introduced HDTV to the US market and the media industry, and, as part of an HDTV task force, she lobbied Congress at the age of 22. In 1995, following her collaboration with Barry Diller to create QVC's Q2, a new home shopping format, Sharkey co-founded iVillage, serving as its chief community architect and head of programming. Becoming the largest online destination for women, iVillage was one of the first major internet media properties, and was sold to NBC Universal for $600 million in 2006.

Sharkey registered the domain names socialmedia.com, socialmedia.net, and socialmedia.org in the late 90s. While there is some debate regarding its genesis, Sharkey is generally acknowledged to be among the first to use the term " social media."

In 1999, after creating the interactive and online brands for Sesame Workshop, Sharkey was recruited by America Online's vice chairman, Ted Leonsis, to join AOL as a senior media executive. At AOL, in addition to overseeing multiple business units, Sharkey led community programming initiatives, including the development of "People Connection" and aol.com. She remained at AOL until 2006, when she was appointed chairman and global president of BabyCenter LLC, a wholly owned subsidiary of Johnson & Johnson.

At BabyCenter, Sharkey built one of the most prominent global destinations for parenting and pregnancy, serving more than 100 million visitors in 22 worldwide markets. Additionally, Sharkey led Johnson & Johnson's initiative with the U.S. State Department for the Mobile Alliance for Maternal Action (MAMA). Announced by US Secretary of State Hillary Clinton, and developed with the cooperation of the White House, MAMA serves women in low-resource settings from South Africa to Bangladesh and India. New and expectant mothers register their due date or their baby's age via mobile phone in order to receive text messages which provide relevant developmental, health, and nutritional information.

In 2013, Sharkey was appointed CEO of Sherpa Foundry. Founded by Shervin Pishevar and Scott Stanford, Sherpa Foundry partners with public companies to identify, define and co-develop ideas and innovations through external resources.

Sharkey additionally serves on public and private boards and advisory committees, and consults to a range of businesses from early to late stage and global public enterprises. Regarded as a thought leader in the practice of consumer insight marketing, Sharkey writes a column on the subject for Forbes.com and blogs for the Huffington Post. She is a speaker at global industry events, conferences and corporate meetings, and is a guest lecturer and mentor at the Stanford Graduate School of Business. Additionally, Sharkey is an active investor in early stage media and technology companies and was included on Business Insider's list of the Top 50 angel and investors.

Sharkey is a 2006 Henry Crown Fellow at the Aspen Institute and a founding and lifetime board member of Baby Buggy, a nonprofit organization which provides essential services to families in need. She lives with her family in Mill Valley, California.
