generation of viewers and provide all-important emergency alert, local news and other programming to consumers across the nation." ION technology vice president Brett Jenkins said, "We're really at a stage like the initial launch of DTV back in 1998. There are almost going to be more transmitters transmitting mobile than receive devices on the market, and that's probably what you'll see for the next six to nine months." Devices would eventually include USB dongles, netbooks, portable DVD players and in-car displays. White House officials and members of Congress saw the triple-play concept in an ION demonstration on July 28, 2009 in conjunction with the OMVC. Another demonstration took place October 16, 2009 with journalists, industry executives and broadcasters riding around Washington, D.C. in a bus with prototype devices. Included were those who would be testing the devices in the Washington and Baltimore markets in January 2010. Progress On August 7, 2009, BlackBerry service began on six TV stations. Eventually 27 other stations are expected to offer the service. By October, 30 stations were airing mobile DTV signals, and that number is expected to grow to 50. Also in the same month, FCC chair Julius Genachowski announced an effort to increase the spectrum available to wireless services. Also in August, WTVE and Axcera began testing a single-frequency network (SFN) with multiple transmitters using the new mobile standard. The RNN affiliate in Reading, Pennsylvania had used this concept since 2007. An amplified antenna or higher power for the transmitting station would likely be needed, as well as repeater stations where terrain is a problem. Lougee, whose company planned testing in its 19 markets in 2010, said the chip designs with the new devices made targeted advertising possible. In December 2009, Concept Enterprises introduced the first mobile DTV tuner for automobiles. Unlike earlier units, this one provides a clear picture without pixelation in a fast-moving vehicle, using an LG M/H chip and a one-inch roof-mounted antenna. No subscription is required. Also in December, the Consumer Electronics Association hosted a "plugfest" in Washington, D.C. to allow manufacturers to test various devices. More than 15 companies, and engineers from different countries, tested four transmission systems, 12 receiver systems, and four software types. On December 1, News Corp. chairman Rupert Murdoch said mobile DTV would be important to the future of all journalism, and he planned to offer TV and possibly newspaper content in this way.
