Eachyear,businessexecutivesaroundtheworldstruggletofindoriginalandcatchynamesfortheircompaniesandtheircompanies’products.Accordingtobusinessexperts,thesedecisionsareamongthemostimportantdecisionsthatfirmsevermake.Anameisthefirstpointofcontactthatacompanyhaswiththeworld,anditcanbeaneffectivemarketingtool.Andrespectednameshavevalue.Whenacompanyissold,thereisoftenafeefortransferringthecompanynametothenewowners.TherightstothenamesIndianMotorcyclesandPanAmAirlinesweresoldyearsafterthosecompanieswentbankrupt.Namesaresoimportantthatsomecompanieshirespecialnamingfirmsthatdevelopalistofnames,testthematfocusgroups,screenthemtobesuretheyareavailable,andthentrademarkthefinalselections.Howdofirmsdecideonnames?Hereareafewofthewayscompaniesplaythenamegame:

Somecompanieschoosestraightforwardnames.Thesemayincludethenameornamesofthefounders(Proctor&Gamble,HewlettPackard),theplacewheretheyfirstdidbusiness(MinnesotaMiningandManufacturing,MutualofNewYork),ortheirprimaryproducts(GeneralElectric,GeneralMotors).Tomakeastraightforwardnamememorable,though,isachallenge.

Somecompaniesaremainlyidentifiedbyinitials.InternationalBusinessMachinesisalmostuniversallycalledIBM,AmericanTelephoneandTelegraphhasbecomeAT&TandKentuckyFriedChickenhasconsciouslychosentobeknownasKFC.Insomecases,though,itisnotexactlyclearwhattheinitialsstandfor:ThecomputercompanyNBI’sinitialsstandfor“NothingButInitials.”O(jiān)rtakethecaseofIKEA,theSwedishdesignfirm:TheinitialsIKcomefromthenameofthefounder,IngvarKomrat.TheEcomesfromthenameofhisfamily

Somecompanieschoosenamesthatareinspiredbyothercompanynames.AccordingtothefounderoftheCarnationEvaporatedMilkCompany,thenameforhisproductwassuggested,strangelyenough,byabrandofcigarsknownasCarnations.SteveJobs,founderofAppleComputers,wasaBeatlesfan,andhenamedhiscompanyafterAppleRecords,thelabelfoundedbytheBeatles.This“borrowing”isperfectlylegalaslongasthetwocompaniesarenotinthesamelineofbusiness.(Reportedly,SteveJobshadtosignanagreementnottoproducerecords.)However,insomecases,companylawyershavesaidthatuseoftheirname,orevenpartoftheirname,resultsin“dilution”ofthestrengthofthatname,andtheyhavesuedothercompaniestopreventthis.Toys-B-Us,forexample,hastriedtoprotectthe“Fi-Us”portionoftheirnameevenwhenithasbeenappliedtocompletelydifferentproducts,suchascheeseorflowersorguns,andMcDonald’shastriedtopreventcompaniesfromusingthe“Mc”prefixthathasbeenusedformanyoftheirproducts.

Somefirmshavechosennamesthathavenothingtodowiththeirbusiness.Appleisnotinthefruitbusiness;itmakescomputers.BedPepperdoesnotsellspices;itsellssoftware.Domino’shasnothingtodowithgames;itmakespizza.Anumberofcompanieshavechosenoff-the-wallorplayfulnamesfortheirproducts.Therearethosenamingexpertswhowarnagainstthis,sayingthatconsumerswillnottaketheseseriously,andinthecaseofB,theymayhavebeenright:Thiswomen’sfashioncompanywentbankruptinnotime.However,M,Google,andYahoo!havesucceededdespite—ormaybebecauseof—theirunusualnames.

Somecorporationshaveturnedtootherlanguagesfornames.AcompanyorproductnamemaycomefromLatin(Aquafinabottledwater,Aviscarrentals,Volvoautomobiles)orGreek(Amphionmultimedia,Oreocookies),Spanish(ElPolloLocofastfoodrestaurants,Fuegotechnology),Danish(Haagen-Dazsicecream),orHawaiian(Akamaiinternettechnology).Othercompaniesborrowfrommythology:Nikeshoes,Ajaxcleanser,andMidasmufflersareallnamedafterfiguresinclassicalmyths.
