2. Telefone igendanwa

Telefone ya mbere yabayeho idakenera umugozi (telefone igendanwa cyangwa mobile), ni iyo mu bwoko bwa Motorola DynaTAC 8000X yafashaga abantu kuvugana bategeranye cyangwa ngo ikenere umugozi.

Iyo telefone ntabwo yakenerega imirongo izihuza cyangwa insinga zambukiranya uturere kugira ngo abantu babashe kuvugana bari kure.

3. Televiziyo

Urubuga www.history.com rwanditse ko televiziyo itahimbwe n’umuntu umwe runaka kuko na mbere y’uko itangira kugaragaza amashusho ahagana mu 1940 na 50, igitekerezo cyo kuyihimba cyari gihari kuva na mbere y’uko ikoranabuhanga ritangira kuzana ibyasaga n’ibitangaza.

Imvano ya televiziyo ishobora kureberwa ahagana mu 1830 na 40 igihe umushakashatsi witwa Samuel F.B.

Indi ntambwe yatewe mu 1876 ubwo Alexander Graham Bell yashyiraga ahagaragara telefone ya mbere ikoresha umugozi abantu bakabasha kuvugana bari kure.

Nyuma nibwo yaje gukorana n’abandi bahanga bagenzi be barimo uwitwa Thomas Edison batangira gutekereza ukuntu noneho bashobora gukora igikoresho cyohereza amshusho n’amajwi icyarimwe.
Ahagana mu 1884 ni bwo umushakashatsi w’Umudage Paul Nipkow yateye intambwe y’ingenzi cyane ari nayo urebye yatumye igitekerezo cyo guhimba televiziyo gishoboka akoresheje uburyo bwo kohereza amashusho yifashishije amadisike yikaraga (spinning discs), ari naho abandi bakomereje bagahimba televiziyo nyirizina.
