Ngaba usakhumbula ezo ntsuku zozuko kwihlabathi leNokia, waza wabizwa ngokuba ngukumkani wefowuni ephathwayo ye-N95? Ngo-1995, bekukho ii-portals ezininzi kwixesha le-2G kwaye kwavela isoftware yoluntu. Ngo-2000, kwixesha le-3G leefowuni ezihlakaniphileyo, isoftware yoluntu yaba ngukumkani. Ngo-2013, kwixesha le-4G, ukusasazwa bukhoma kunye neevidiyo ezimfutshane zazithandwa ngokulinganayo, kwaye ukuhamba kolwazi kwaba ngumxholo oshushu. Xa ndijonga emva kungekudala izolo, ubomi bedijithali buye buze kuthi, kwaye iifowuni eziphathwayo, iTV nayo iyaphucuka. Iseti yeTV emnyama nemhlophe eyayikade ingaqhelekanga ithathelwe indawo yiTV yeLCD enemibala, esivumela ukuba sibukele ihlabathi ekhaya. Phakathi kwazo, iteknoloji kunye nesantya sophuhliso lweTV yodwa sinomtsalane omkhulu, kodwa namhlanje ndifuna ukuthetha kungekuko ngetekhnoloji yeTV, kodwa ngolawulo olukude oluhamba nayo.
Uphuhliso lolawulo olukude lunokulandelwa emva kwiminyaka yoo-1950.
Ngo-1950, i-CEO yeZenith electronics uJohn McDonald wacela umngeni kwiinjineli zakhe ukuba zize nesixhobo esinokuvala iintengiso okanye sizithumele kwenye itshaneli.
Ulawulo olukude lwazalwa.
Ekuqaleni, yayinokuxhunywa kwiTV yakho kuphela. Kwiminyaka emihlanu kamva, u-Eugene Polley, injineli kwinkampani efanayo, wavelisa isixhobo sokuqala esingenazingcingo esilawulwa ngombane wokukhanya esibizwa ngokuba yi-flashmatic, esamenza wafumana isihloko sokuba nguyise wolawulo olukude lweTV.
Kodwa ezi zixhobo, ezinokutshintsha iitshaneli kwaye zilungise ivolumu, azisetyenziswa kakhulu kuba kunzima ukuzilawula.

Emva koko, ngo-1956, uRob Adler waphuhlisa ulawulo olukude lweZenith Space Command. Lusebenzisa umgaqo we-ultrasound ukulungisa ivolumu kunye netshaneli. Isitshixo ngasinye sikhupha i-frequency eyahlukileyo, kodwa isixhobo siphantsi kokuphazamiseka okuqhelekileyo kwe-ultrasound.
Kude kube ngu-1980, kwazalwa ulawulo olukude lwe-infrared, kwaye lwathatha indawo yesixhobo solawulo lwe-ultrasonic kancinci kancinci. Ulawulo olukude lwe-infrared kukusetyenziswa kokukhanya kwe-infrared ukuhambisa imiyalelo, oko kukuthi, singamaqhosha amade aqhelekileyo olawulo olukude.
Uphuhliso lolawulo olukude ukuza kuthi ga ngoku, abavelisi abaninzi be-remote control baqalise imisebenzi eyahlukeneyo, kubandakanya ulawulo lwelizwi, olukwaziwa ngokuba yi-Bluetooth voice remote control, kufuneka bacinezele iqhosha lelizwi le-remote control ukuze bathethe neTV, ukuqondwa kweTV kuya kusebenza ngaxeshanye. Kodwa ngokuqinisekileyo oko akuzange kufezekise injongo engenazandla de ezinye iimpawu zaqala ukubonelela ngezakhono zokunxibelelana ngezwi ezikude ezikuvumela ukuba ulawule iTV yakho nge-wake word ngaphandle kokufuna i-remote.
