aQuantive was then purchased by Microsoft in 2007, and then subsequently sold to Publicis Groupe in 2009.

That company was then acquired by aQuantive in 2004, and merged into Avenue A | Razorfish. Assets from Scient were purchased by SBI Group in 2003, and merged into Razorfish. In July 2002 the joint company filed for bankruptcy. In November 2001, iXL merged with former competitor Scient, with the two companies operating under the Scient name, but the leftovers were rebranded as Creative Bubble. Notable clients included GE, Delta Air Lines, Budget Rent-A-Car, Chase Bank, Merrill Lynch, The Home Depot, FedEx and WebMD. It was part of what some in the industry called 'The Fast Five', a group of 'e-consultancies' that also included Razorfish, Scient, Viant and USWeb/CKS. Ultimately, though, Khan Academy is accessible for free, while IXL is a. Students will enjoy learning with IXLs fun and interactive questions, including graphing, drag-and-drop, select-and-edit and more. Yes, IXL has deeper analytics, more adaptive questions and can create a more personalized learning path for kids, but it is a paid solution. IXL offers online maths practice covering preschool through year 12 maths and everything in between. Many of these offices started out as local interactive agencies that were purchased by iXL, such as Micro Interactive, which became the New York office. Finally, when it comes to price the difference between IXL and Khan Academy is pretty straightforward and obvious. The company also had smaller 'satellite offices' in Amsterdam, Dallas and Memphis, Tennessee. IXL had its headquarters in Atlanta, with additional offices in Berlin, Boston, Charlotte, Chicago, Denver, Hamburg, London, Los Angeles, Madrid, New York City, Richmond, San Diego, San Francisco, São Paulo, Tokyo and Washington, D.C. After a series of acquisitions, it is now part of the Razorfish agency, owned by Publicis Groupe. At the company's height in 1999, which coincided with the height of the dot-com boom, iXL had around 1500 employees, a quarterly revenue of $33 million, and was publicly traded on the Nasdaq exchange, with ticker symbol 'IIXL'. The company was founded by Atlanta entrepreneur Bert Ellis, who also served as the company's chairman and CEO. IXL Enterprises was an international interactive agency that operated from 1996 until 2002.
