In 1996-ish timeframe, Sun paid about $150 Million USD to either  
Univel or Novell or someone to have a permanent license/right to SVR4  
UNIX.  Dunno if it was SVR4.0 or 4.2 codebase or all 4.x releases.

 From that point on, it was clear that Sun was going to put all their  
wood behind the one arrow of Solaris, and they have continued to do

Sun was working on Solaris 2.0  well before they bought Interactive.   
In 1988 ATT and Sun announced they would work together to put out  
SVR4.  They didn't buy Interactive until about 1992.  And Interactive  
ran only on x86 rather than on SPARC machines.

(Even DELL had a version of SVR4.0 back in the day.)
