United Online announced a preliminary plan to separate into two independent, publicly traded companies, one of which will include its NetZero 4G Mobile Broadband business. United said one of companies will keep the United Online name and will continue to operate the businesses of the company's Content & Media and Communications segments, whose brands include NetZero, Classmates and Juno. The other company will be FTD, which will include the domestic and international operations of the company's FTD segment, which includes the FTD and Interflora brands. United said it also is reviewing strategic alternatives for its Content & Media and Communications businesses, including potentially spinning-off the Content & Media segment as an additional separate, publicly traded company. NetZero, a low-cost Internet service provider, released its prepaid mobile broadband service in March. The service runs on Clearwire's (NASDAQ:CLWR) WiMAX network and offers low prices--including a tier of free service--and data download speeds to 10 Mbps.
