Would you Watch if it was free?

At the three carriers that offer mobile TV services--AT&T ( NYSE: T), Verizon ( NYSE: VZ), and Sprint--consumers must pay either a monthly fee, or a pay-per-view charge. But there's growing evidence from other countries where mobile TV broadcasts are available for free that it's that little inconvenience of having to pay that prevents consumers from watching, not their short attention spans or the size of mobile phone screens. In Japan, free TV broadcasts killed off the Toshiba-backed paid mobile TV service Moba-Ho! just a few weeks ago, while in Germany, there have been press reports that subscription TV venture Mobile 3.0 will be forced to shut down after operators threw their support behind DVB-T technology that lets users view digital terrestrial TV for free.
