organized that same year by Marks and Wurman with help from Dr. Frank Stanton, featured demos of the compact disc, co-developed by Philips and Sony and one of the first demonstrations of the Apple Macintosh computer. Presentations were given by famous mathematician Benoit Mandelbrot and influential members of the digerati community, like Nicholas Negroponte and Stewart Brand. The event was financially unsuccessful; hence, it took six years before the second conference was organized. TED2 was held at the Monterey Conference Center in California in 1990. From 1990 onward, a growing community of "TEDsters" gathered annually with Wurman leading the conference in Monterey until 2009, when it was relocated to Long Beach, California, due to a substantial increase in attendees. Initially, the speakers had been drawn from the fields of expertise behind the acronym TED, but during the 1990s, the roster of presenters broadened to include scientists, philosophers, musicians, religious leaders, philanthropists, and many others. 2000–present: Recent growth In 2000, Wurman, looking for a successor at age 65, met with new-media entrepreneur and TED enthusiast Chris Anderson to discuss future happenings. Anderson's UK media company Future bought TED. In November 2001, Anderson's non-profit The Sapling Foundation (motto: "fostering the spread of great ideas") acquired TED from Future for £6m. In February 2002, Anderson gave a TED Talk in which he explained his vision of the conference and his future role of curator. Wurman left after the 2002 conference. In 2006, attendance cost was $4,400 per person and was by invitation only. The membership model was shifted in January 2007 to an annual membership fee of $6,000, which includes attendance of the conference, club mailings, networking tools, and conference DVDs. The 2018 conference was $10,000 per attendee. Between 2001 and 2006, TED upgraded its platform to have TED talks online for free, added TEDGlobal that became a worldwide conference, and created the TED prize. In 2014, the conference was relocated to Vancouver, British Columbia, Canada. TED is currently funded by a combination of various revenue streams, including conference attendance fees, corporate sponsorships, foundation support, licensing fees, and book sales. Corporate sponsorships are diverse, provided by companies such as Google, GE, AOL, Goldman Sachs, and The Coca-Cola Company. Sponsors do not participate in the creative direction of the event, nor are they allowed to present on the main stage, in the interests of independence. In 2015, TED staff consisted of about 180 people
