By the early 1980s, tens of millions of home computers were running some variation of Microsoft BASIC, which had become the "de facto" standard. The ANSI efforts eventually became pointless, as it became clear that these versions were not going to have any market impact in a world dominated by MS. Both versions were eventually ratified, but saw little or no adoption and the standards were later withdrawn. Kemeny and Kurtz, however, decided to continue their efforts to introduce the concepts from SBASIC and the ANSI Standard BASIC efforts. This became True BASIC.
