LG and Samsung are Korean rivals, not the same company!
Personally I wouldn't mind selling the stadium rights if it got more revenue. End of the day the team is more important than stadium name and we would still call if SoL anyway.
As Bumblebore said, if we could incorporate LG into the existing name everyone would be happy.
Hence the question mark!
I do know that LG TV's are made in Samsung factories though, with Samsung parts, so there's some kinda partnership for sure.
