What if Sony acquired MGM/UA back in 1986?

as of 2019, MGM Holdings is one of the major media companies to be independently owned rather than owned by a larger company (e.g: Viacom and CBS Corporation by National Amusements, NBCUniversal by Comcast, WarnerMedia by AT&T and Columbia Pictures by Sony).

However, Sony made a buying on MGM in 2005.
