Usakhumbula lezo zinsuku zenkazimulo emhlabeni weNokia, futhi yaqanjwa njengenkosi yeselula ye-N95? Ngo-1995, bekunamaphothali amaningi enkathini ye-2G futhi kwavela isoftware yezenhlalo. Ngo-2000, enkathini ye-3G yamafoni ahlakaniphile, isofthiwe yezenhlalakahle yaba yinkosi. Ngo-2013, ngesikhathi se-4G, ukusakazwa bukhoma namavidiyo amafushane athandwa ngokulinganayo, futhi ukugeleza kolwazi kwaba isihloko esishisayo. Uma sibheka emuva kungekude kakhulu izolo, impilo yedijithali ithule ifikile kithi, nomakhalekhukhwini, i-TV nayo iyathuthuka. Isethi ye-TV eyake yaba yinhlese emnyama nemhlophe ithathelwe indawo ngombala we-LCD TV, okusivumela ukuthi sibukele umhlaba sisekhaya. Phakathi kwabo, ubuchwepheshe kanye nesivinini sokuthuthukiswa kwe-TV kuphela kunesikhalo esikhulu, kodwa namuhla ngifuna ukukhuluma hhayi ngobuchwepheshe be-TV, kodwa isilawuli kude esihambisana nayo.
Ukuthuthukiswa kokulawula kude kungalandelelwa emuva kuma-1950s.
Ngo-1950, isikhulu se-zenith electronics uJohn McDonald waphonsela inselelo onjiniyela bakhe ukuthi beze nethuluzi elingathulisa izikhangiso noma liziqondise kwesinye isiteshi.
I-remote control yazalwa.
Ekuqaleni, ingaxhunywa ku-TV yakho kuphela. Ngemva kweminyaka emihlanu, u-Eugene Polley, unjiniyela enkampanini efanayo, wakha idivayisi yokuqala engenantambo elawulwa yi-light-beam ebizwa ngokuthi i-flashmatic, eyamenza wabizwa ngokuthi uyise wesilawuli kude sethelevishini.
Kodwa imishini, ekwazi ukushintsha iziteshi futhi ilungise ivolumu, ayisetshenziswa kakhulu ngoba kunzima ukuyilawula.

Kwathi ngo-1956, uRob Adler wasungula isilawuli kude seZenith Space Command. Isebenzisa isimiso se-ultrasound ukulungisa ivolumu nesiteshi. Ukhiye ngamunye ukhipha imvamisa ehlukile, kodwa idivayisi ingaphansi kokuphazanyiswa okuvamile kwe-ultrasonic.
Kuze kube ngu-1980, kwazalwa isilawuli kude se-infrared, futhi kancane kancane sashintsha idivayisi yokulawula i-ultrasonic. Isilawuli kude se-infrared ukusetshenziswa kokukhanya kwe-infrared ukudlulisa iziqondiso, okungukuthi, siyizinkinobho ezinde ezivame kakhulu zesilawuli kude.
Ukuthuthukiswa kwesilawuli kude kuze kube manje, abakhiqizi abaningi besilawuli kude bethule imisebenzi ehlukene, okuhlanganisa isilawuli sezwi, esikwaziwa nangokuthi isilawuli kude sezwi se-Bluetooth, badinga nje ukucindezela ukhiye wezwi wesilawuli kude ukuze ukhulume ne-TV, ukuqashelwa kwe-TV kuzosetshenziswa. ngesikhathi esifanayo. Kodwa lokho akuzange kufinyelele umgomo we-hands-free kwaze kwaba yilapho ezinye izinhlobo zemikhiqizo ziqala ukuhlinzeka ngamakhono okuxhumana ezwi akude akuvumela ukuthi ulawule i-TV yakho ngezwi lokuvuka ngaphandle kokuthi uthole isilawuli kude.
