DEVELOPI G OF ELECOMMU ICA IO S La e i he i e ee h ce ury commu ica io s facili ies were augme ed by a ew i ve io – elepho e. I he USA i s use slowly expa ded, a d by 1900 he America elepho e a d elegraph Compa y co rolled 855,000 elepho es; bu elsewhere he elepho e made li le headway u il he we ie h ce ury. Af er 1900, however, elepho e i s alla io s ex e ded much more rapidly i all he weal hier cou ries. he umber of elepho es i use i he world grew a almos 100 per ce per decade. Bu lo g-dis a ce elepho e services gradually developed a d bega o compe e wi h elegraphic busi ess. A grea er co ribu io o lo g-ra ge commu ica io came wi h he developme of wireless. Before he ou break of he Firs World War wireless elegraphy was es ablished as a mea s of regular commu ica io wi h ships a sea, a d provided a valuable suppleme o exis i g elegraph li es a d cables. I he ex few years he elepho e sys ems of all he chief cou ries were co ec ed wi h each o her by radio. Far more immedia e was he i flue ce ha radio had hrough broadcas i g a d by elevisio , which followed i a a i erval of abou we y-five years. elepho es are as much a form of i fras ruc ure as roads or elec rici y, a d compe i io will make hem cheaper. Losses from lower prices will be cou ered by higher usage, a d ax reve ues will be efi from he fas er eco omic grow h ha elepho es bri g abou . Mos impor a of all, by cu i g ou he eed o i s all cos ly cables a d microwave ra smi ers, he ew elepho es could be a boo o he remo e a d poor regio s of he ear h. Eve oday, half he world’s popula io lives more ha wo hours away from a elepho e, a d ha is o e reaso why hey fi d i hard o break ou of heir pover y. A farmer’s call for advice could save a whole crop; access o a ha dse could help a small rural busi ess sell i s wares. A d i rich places wi h reaso able elepho e sys ems already i place, he effec of ew e ra s – he replaceme of bad, overpriced services wi h clever, cheaper o es – is less drama ic bu s ill co siderable. Global pho es are o goi g o deliver all hese be efi s a o ce, or easily. I deed, if he marke fails o develop, i could prove oo small o suppor he cos s of lau chi g sa elli es. S ill, ha is a risk wor h aki g. A d hese ew global elepho es reflec a wider re d.

Sa elli e elepho es will be able o make calls from a ywhere o ear h o a ywhere else. ha could make hem especially useful o remo e, hird-world villages (some of which already use s a io ary sa elli e elepho es), explorers a d disas er-relief eams. oday’s mobile pho es depe d o ear h-bou d ra smi ers, whose ech ical s a dards vary from cou ry o cou ry.
