Because IBM wanted to build a computer with an 8-bit data bus. The 8086 and 8088 are the same processor, with the 8086 running on a 16-bit data bus, and the 8088 running on an 8-bit data bus. This allowed IBM to make the most use of older designs that supported 8-bit data buses, such as the 8080, the 8085, and the Z80.
1978 - 8086 1979 - 8088 First IBM PC used 8088. I think later low end IBM PC's used 8086.

No remotely modern motherboard is compatible with an 8086 processor. The old IBM PC clones from the early to mid 1980s would have been the only motherboards to support the 8086.

IBM did not create the PC. IBM attempted to gain a PC foothold years ago but was not very successful.
IBM sold its PC business to Lenovo in 2004.
The first IBM PC is the Compaq Portable.
IBM PC Convertible was created on 1986-04-03.
Because that's what Intel chose to do. The 8086 was released in 1978. The 8088 was released in 1979, and it was the same 16 bit processor core, but running on a 8, instead of a 16, bit bus, making it more tenable in low end, cheap, systems, such as the IBM PC.

The IBM General Purpose Interface Bus (GPIB) Adapter connects IBM Personal Computer (PC) products to a general-purpose interface bus.
