Why a byte is equal to 8 bits?

IBM created the word "byte" on the Stretch Project. It was a variable length data element originally defined as 1 to 16 bits in length. Most computers of the time used characters that were 6 bits in length, but this allowed only for uppercase letters. Because the byte was to be used for binary bits (1 bit in length), decimal digits in arithmetic (4 bits in length), baudot characters used by teletypes of the time (5 bits in length), standard characters (6 bits in length), various extended characters with both uppercase & lowercase letters as well as foreign language characters if needed (up to 16 bits in length), and other sizes for special applications; the variable length feature of the byte was seen as essential for orthogonality in the instruction set for all data elements smaller than a full 64 bit binary word.Unfortunately as the project proceeded and architectural and instruction set decisions were being finalized, it was realized that there were not enough bits available in the instruction words that processed byte data for a length field for the full range of 1 to 16 bits. The decision was made to use a smaller length field and reduce the range to 1 to 8 bits. This should still be adequate for everything from binary bits to decimal digits to extended characters, the lost range did not bother the potential customers. Bytes could span the boundaries between 64 bit words (i.e. start in one word and finish in the next).The finished machine, the IBM 7030 Stretch, was delivered in 1961. However it had performance problems and IBM discontinued the model when the original 9 orders had been filled without taking anymore orders.When IBM began work on what was to become the System 360 family of compatible computers, they decided to include the concept of the "byte" but decided that making it variable length as it was in the 7030 added too much circuit complexity and cost which would be unacceptable in lower end models of the 360. IBM decided to use the maximum size of the 7030 byte (8 bits) as the size in the System 360, also bytes had to all be aligned on byte boundaries with the full 32 bit binary word to further simplify the addressing circuits.The resulting family of computers were announced in 1964, with initial models beginning delivery in 1965.Other computer manufacturers soon started copying IBM and began using the byte in their machines and the 8 bit byte became a defacto industry standard.
