The sign in Hopkinton Green that commemorates the marathon reads WELCOME TO HOPKINTON. IT ALL STARTS HERE. Actually, it all started down the road in Ashland on Patriots' Day April 19,1897, when 15 men from the Boston area and New York City entered the first Boston Athletic Association Marathon. A 22-year-old lithographer from New York named John McDermott won the race, though not easily. A few miles from the finish McDermott had to stop because of intense leg cramps. Fortunately, he had an attendant who answered McDermott's command, "Rub!" and he crossed the finish line in 2:55:10—which would have been good enough for683rd place in last year's Boston Marathon.
Times have changed, of course. The road to Boston is now paved. The leather shoes that McDermott wore gave way to canvas sneakers that gave way to leather shoes. The start was moved from Ashland to Hopkinton in 1924 in order to lengthen the course to the classic marathon distance. And in recent years, the traditional post-marathon beef stew served by the BAA has been replaced by a pre-marathon pasta party sponsored by Ronzoni. But from the beginning, Boston has been immensely popular: the seventh running of the marathon in 1903 attracted 200,000 spectators. This year an estimated 1.5 million will cheer the runners on as they move from Hopkinton to Ashland to Framingham to Natick to Wellesley to... "Its obvious strength is 100 years of the best runners in the world," says Bill Rodgers, the folk hero who has won Boston four times. "But it is also the best course anywhere. You run through small towns on your way to Boston. You really have a sense of making progress."
If Boston has a patron saint, it is John A. Kelley, who first ran the race in 1928 when he was 20 and last ran the race in 1992 when ha was 84. In 1935 Kelley, who was then a floral assistant outdueled toolmaker Pat Dengis, eliciting this response from Dengis: "Would you imagine this, a florist runs 26 miles for a laurel wreath!" Though he received a police escort home to Arlington, Massachusetts, and a telegram from the Governor, Kelley was back at work the next day, preparing Easter lilies at Anderson's Florist Shop. He also won in 1945 at the advanced age of 37 and told a reporter, "Life merely begins at 40, and I have three years to go." Kelley no longer runs in the marathon, but runners can still pass him on Heartbreak Hill in Newton, where there are twin statues of Kelley—as he ran in his first victory and as he ran in his 61st Boston.
This passage is mainly about ______.
A．the most important runners in marathon history
B．the history of the Boston Marathon
C．a bizarre rite held in the tiny town of Hopkinton
D．the process of the marathon event
"This is a really exciting time—a new era is starting," says Peter Bazalgette, the chief creative officer of Endemol, the television company behind "Big Brother" and other popular shows. He is referring to the upsurge of interest in mobile television, a nascent industry at the intersection of telecoms and media which offers new opportunities to device-makers, content producers and mobile- network operators. And he is far from alone in his enthusiasm.
Already, many mobile operators offer a selection of television channels or individual shows, which are " streamed" across their third-generation (3G) networks. In South Korea, television is also sent to mobile phones via satellite and terrestrial broadcast networks, which is far more efficient than sending video across mobile networks; similar broadcasts will begin in Japan in April. In Europe, the Italian arm of 3, a mobile operator, recently acquired Canale 7, a television channel, with a view to launching mobile-TV broadcasts in Italy in the second half of 2006. Similar mobile-TV networks will also be built in Finland and America, and are being tested in many other countries.
Meanwhile, Apple Computer, which launched a video-capable version of its iPod portable music-player in October, is striking deals with television networks to expand the range of shows that can be purchased for viewing on the device, including "Lost", "Desperate Housewives" and "Law & Order". TiVo, maker of the pioneering personal video recorder (PVR), says it plans to enable subscribers to download recorded shows on to iPods and other portable devices for viewing on the move. And mobile TV was one of the big trends at the world's largest technology fair, the Consumer Electronics Show, which took place in Las Vegas this week.
Despite all this activity, however, the prospects for mobile TV are unclear. For a start, nobody really knows if consumers will pay for it, though surveys suggest they like the idea. Informa, a consultancy, says there will be 125 million mobile-TV users by 2010. But many other mobile technologies inspired high hopes and then failed to live up to expectations. And even if people do want TV on the move, there is further uncertainty in three areas: technology, business models and the content itself.
