of television broadcasting,a somewhat similar development is takingplace in Bell System television program fa-cilities—of which radio relay forms thelarger part. Beamed from tower to toweracross the country with the speed of light,television images as well as telephone mes-sages are transmitted over a network whichhas grown to more than 60,000 channel miles of radio relay facilities in the last fiveyears. Today the major activity is in pro-viding extensions to the backbone routes,to carry the programs into more and morecommunities in many parts of the country.The map two pages over shows how muchthe network has grown—more than ig,ooochannel miles—in the past nine months,and the pictures give some indication ofwhat is involved in making these newestfacilities for telephone and television serv-ice available to more people in more places.And now the art progresses further—aswitness the transmission of PasadenasTournament of Roses parade across thecontinent on January i in color.
