Assuming you mean the multihoming of using multiple "upward" direction 
networks to ensure continuous availability of transit, that was already 
established practice when I built my first one in 1989.

So it predated the modern NII / IXP architecture and the transit / 
peering distinction.  So at that time there was no clear direction "up" 
but more just generally "backboneward" since the backbone didn't have a 
specific center, and multihoming didn't necessarily mean toward that 
center because transit cones hadn't yet been defined.

BGP was standardized in 1989.  EGP as a subset of GGP in 1982.
