Susan Diane Wojcicki is a Polish-American business executive who is the CEO of YouTube. She has been in the tech industry for over 20 years. Wojcicki was involved in the founding of Google, and became Google's first marketing manager in 1999. She later led the company's online advertising business and was put in charge of Google's original video service. After observing the success of YouTube, Wojcicki proposed the acquisition of YouTube by Google in 2006, and has served as CEO of YouTube since 2014. She also co-developed and launched Google Image Search with engineer Huican Zhu. In 2003, Wojcicki helped lead the development of one of Google's seminal advertising products—AdSense. She served as its first product manager, and for her efforts, was awarded the Google Founders' Award. She rose to become Google's senior vice president of Advertising & Commerce, and oversaw the company's advertising and analytic products, including AdWords, AdSense, DoubleClick, and Google Analytics. YouTube, then a small start-up, was successfully competing with Google's Google Video service, overseen by Wojcicki. Her response was to propose the purchase of YouTube. She handled two of Google's largest acquisitions — the $1.65 billion purchase of YouTube in 2006 and the $3.1 billion purchase of DoubleClick in 2007.
