For lovers of 1.5-inch TV, Cingular is launching an on-demand mobile-TV service, Cingular Video, running over the company's new 3G wireless network. Subscribers can view three- to five-minute clips from 18 different channels, including Cartoon Network, NBC, ESPN, and HBO. Cingular Video comes free with an unlimited 3G package ($19.99 per month); premium content, like clips from HBO's Entourage or The Sopranos, costs an additional $4.99 per month. Service providers are hoping video subscriptions can help recoup billions spent on building 3G networks. Verizon offers its VCast service for $15 a month, and Sprint Nextel's service costs between $20 and $30, depending on the subscriber's package. The only question: once the novelty wears off, does anyone really want to watch a miniature Tony Soprano for three minutes? — Trevor Noren
