Wali ma xasuusataa maalmihii sharafta lahaa ee adduunka Nokia, waxaana loogu magac daray boqorka taleefanka gacanta ee N95? Sannadkii 1995, waxaa jiray bogag badan xilligii 2G waxaana soo baxay barnaamijyo bulsheed. Sannadkii 2000, xilligii 3G ee taleefannada casriga ah, barnaamijyada bulshadu waxay noqdeen boqorka. Sannadkii 2013, xilligii 4G, daawashada tooska ah iyo fiidiyowyada gaagaaban ayaa si isku mid ah caan u ahaa, socodka macluumaadkana wuxuu noqday mowduuc kulul. Markii aan dib u milicsanay shalay, nolosha dijitaalka ah si deggan ayay noogu timid, taleefannada gacantana, TV-gu sidoo kale wuu casriyeynayaa. Telefishanka madow iyo caddaanka ah ee mar ahaa mid caajis ah ayaa lagu beddelay LCD TV midab leh, taasoo noo oggolaanaysa inaan adduunka ku daawanno guriga. Kuwaas waxaa ka mid ah tignoolajiyada iyo xawaaraha horumarinta TV-ga oo keliya ayaa leh soo jiidasho weyn, laakiin maanta waxaan rabaa inaan ka hadlo maaha tignoolajiyada TV-ga, laakiin xakamaynta fog ee la socota.
Horumarinta xakamaynta fog waxaa dib loogu soo celin karaa 1950-meeyadii.
Sannadkii 1950, madaxa shirkadda elektaroonigga ee Zenith, John McDonald, ayaa ku boorriyay injineeradiisa inay la yimaadaan qalab joojin kara xayaysiisyada ama u wareejin kara kanaal kale.
Kontoroolka fog ayaa dhashay.
Markii hore, waxaa lagu xiri karaa TV-gaaga oo keliya. Shan sano ka dib, Eugene Polley, oo ah injineer ka tirsan isla shirkaddaas, ayaa sameeyay qalabkii ugu horreeyay ee wireless-ka ee la xakameeyo iftiinka oo loo yaqaan flashmatic, kaas oo u horseeday inuu noqdo aabaha qalabka fog ee telefishanka.
Laakiin aaladaha, kuwaas oo beddeli kara kanaalada oo hagaajin kara mugga, si weyn looma isticmaalo sababtoo ah way adag tahay in la xakameeyo.

Kadib, sannadkii 1956, Rob Adler wuxuu sameeyay xakamaynta fog ee Zenith Space Command. Waxay isticmaashaa mabda'a ultrasound si loo hagaajiyo mugga iyo kanaalka. Fure kastaa wuxuu soo saaraa soo noqnoqosho kala duwan, laakiin qalabku wuxuu ku dhacaa faragelin ultrasonic caadi ah.
Ilaa 1980, xakamaynta fog ee infrared-ka ayaa dhalatay, waxayna si tartiib tartiib ah u beddeshay aaladda xakamaynta ultrasonic-ka. Xakamaynta fog ee infrared-ka waa isticmaalka iftiinka infrared-ka si loo gudbiyo tilmaamaha, taas oo ah, waxaan nahay badhamada dhaadheer ee ugu badan ee xakamaynta fog.
Horumarinta xakamaynta fog ilaa hadda, soosaarayaal badan oo ka tirsan xakamaynta fog ayaa bilaabay hawlo kala duwan, oo ay ku jiraan xakamaynta codka, oo sidoo kale loo yaqaan xakamaynta fog ee codka Bluetooth, waxay u baahan yihiin oo keliya inay riixaan furaha codka ee xakamaynta fog si ay ula hadlaan TV-ga, aqoonsiga TV-ga ayaa isla waqtigaas la shaqeyn doonaa. Laakiin taasi hubaal ma aysan gaarin yoolka gacanta laga bilaabo ilaa qaar ka mid ah noocyada ay bilaabeen inay bixiyaan awoodaha is-dhexgalka codka fog ee kuu oggolaanaya inaad ku xakamayso TV-gaaga erey toos ah adigoon waligood helin qalabka fog.
