经过近百年的发展，电视与体育已经紧紧地拥抱在了一起。尽管它们之间矛盾重重，但利益使它们靠得更近。没把电视当回事电视的出现比现代奥运会的诞生晚了４０年，但是电视在普及体育运动、传播奥林匹克精神方面，无疑起到了决定性作用。用电视转播奥运会比赛实况，开始于１９
After nearly a hundred years of development, television and sports have been embraced tightly together. In spite of the contradictions between them, the benefits keep them closer together. Television did not take TV seriously. The emergence of television was 40 years behind the birth of the modern Olympics. However, television undoubtedly played a decisive role in popularizing sports and spreading the Olympic spirit. Broadcast the Olympics live on TV, starting at 19
