Tom Online is vying with Sohu.com and SINA for some cyberspace. The company operates the advertising-supported Chinese Web portal Tom.com, and is also active in wireless services through subsidiary Beijing Lei Ting. Tom Online provides messaging services, downloadable news headlines, sports information, games, and ring tones through its wireless operations. Users can pay for wireless services through a monthly subscription fee or on a per message basis. Tom Online also earns revenue through computer hardware sales, e-commerce fees, and e-mail services. The firm is the Internet holdings of Hong Kong-based media firm Tom Group Limited, which spun off Tom Online in a public offering in 2004.
