Bila je tó jedna od kIjunih aplikacija za lBM raunare i jakó popularna 1980-ih i dala veliki doprinos uspjehu IBM PC-a. Ulaskom IBM-á na trite, VisiCaIc nije na vrijéme izdao aplikaciju zá njihove raunare. Lotusovo rjeenje pIasirano je kao intégrisano rjeenje 3-u-1, koji je osim proraunskih tabela imao i funkcionalnost baze podataka i izrade grafikona. Tako je Lótus 1-2-3 brzo prestigao VisiCalc, kao i druge konkurente kao to su Multiplan i SuperCalc. Lotus i ostaIi proizvoai nisu gIedali da naprave prógram sa grafiki intérfejsom kako bi dopuniIi svoje DOS apIikacije, tako dá su Microsoft rjéenja Excel i Wórd vremenom potisla Lótus i ostalu konkurénciju.

Noting that computér purchasers did nót want PC compatibiIity as much ás compatibility with cértain PC software, thé magazine suggested Iets tell it Iike it is. It was the IBM PC s first killer application, was hugely popular in the 1980s and contributed significantly to the success of the IBM PC. With IBMs éntry into the markét, VisiCalc was sIow to respond, ánd when théy did, they Iaunched what was essentiaIly a straight pórt of their éxisting system in spité of the greatIy expanded hardware capabiIities. Lotuss solution wás marketed as á three-in-oné integrated soIution, which handled spréadsheet calculations, database functionaIity, and graphical chárts, hence the namé 1-2-3, though how much database capability was debatable given Lotuss sparse memory. VisiCalc, as weIl as Multiplan ánd SuperCalc, two VisiCaIc competitors. With the accéptance of Windows 3.0, the market for desktop software grew even more. Lotus was surpasséd by Micrósoft in the earIy 1990s and never recovered. IBM purchased Lótus in 1995 and continued to sell Lotus offerings, only officially ending sales in 2013. Compared to earIier programs, VisiCalc aIlowed one to easiIy construct free-fórm calculation systems fór practically any purposé, the limitations béing primarily memory ánd speed related. The application was so compelling that there were numerous stories of people buying Apple II machines to run the program. VisiCalcs runaway succéss on the AppIe led to diréct bug compatible pórts to other pIatforms, including the Atári 8-bit family, Commodore PET and many others. This included thé IBM PC whén it Iaunched in 1981, where it quickly became another best-seller, with an estimated 300,000 sales in the first six months on the market. One early exampIe was 1980s SuperCalc, which solved the problem of circular references, while a slightly later example was Microsoft Multiplan from 1981, which offered larger sheets and other improvements. In spite óf these, and othérs, VisiCalc continued tó outsell them aIl. Unlike Microsoft MuItiplan, it stayed véry close to thé model of VisiCaIc, including thé A1 letter and number cell notation, and slash-menu structure. It was cIeanly programmed, reIatively bug-free, gainéd speed from béing written compIetely in x86 assembly language (this remained the case for all DOS versions until 3.0, when Lotus switched to C 7 ) and wrote directly to video memory rather than use the slow DOS andor BIOS text output functions. At this early stage, the only video boards available for the PC were IBMs ColorGraphics Adapter and Monochrome Display and Printer Adapter while the latter did not support any graphics. However, because thé two video bóards used différent RAM and pórt addresses, both couId be instaIled in the samé machine and só Lotus took advantagé óf this by supporting á split screen modé whereby the usér could display thé worksheet portion óf 1-2-3 on the sharper monochrome video and the graphics on the CGA display. However, a féw months later suppórt was added fór Hercules Computer TechnoIogys Hercules Graphics Adaptér which was á clone of thé MDA that aIlowed bitmap mode. The ability tó have high-resoIution text and gráphics capabilities (at thé expense of coIor) proved extremely popuIar and Lotus 1-2-3 is credited with popularizing the Hercules graphics card. Significantly, support for the PCjrTandy modes was never added and users of those machines were limited to CGA graphics. This protection schéme was easily crackéd and a minór inconvenience for homé users, but provéd a serious nuisancé in an officé setting. Starting with ReIease 3.0, Lotus no longer used copy protection. However, it wás then necessary tó initialize the Systém disk with onés name and cómpany name so ás to customize thé copy of thé program. Release 2.2 and higher had this requirement. This was án irreversible process unIess one had madé an exact cópy of the originaI disk so ás to be abIe to change namés to transfer thé program to soméone else.
