ARRIS, HBO, iN DEMAND, Rovi, SeaChange International, Synacor and thePlatform are sponsoring student teams from seven U.S. business schools in a contest this fall to create marketing and launch plans for new video innovations. The student teams comprise graduate candidates in top MBA university programs, including Boston University School of Management, Columbia Business School, Georgetown McDonough, Howard University School of Business, MIT Sloan, NYU Stern and Pace Lubin. The competition concludes at the 2nd annual Cable Interacts Interactive Launch Competition, set for Nov. 28 New York City; student teams will make their presentations before a panel of industry experts and top executives. Here’s how it works: Each team is presented with a case study about a fictitious cable company deploying their sponsor company’s product to provide new video services for their cable customers. The teams get the opportunity to work with their sponsor company to develop their launch plan, including a business model and marketing campaign. The judges will determine the best launch plans, and will award first-, second- and third-place winners. Teams win cash prizes and will gain visibility toward a potential career in cable, broadband, television or related fields…The Wireless Broadband Alliance has 14 new members: Alvarion, AlwaysOn, BandwidthX, Belgacom International Carrier Services (BICS), Crown Castle, Front Porch, Huawei Technologies, Hutchison Global Communications, NTT Broadband Platform, Netgem, Quadriga Worldwide, Sysnet Integrators and Towerstream. The membership now totals 95.
