MGM Television is a company founded by Metro-Goldwyn-Mayer in 1955. There are a lot of versions of this logo, including the 1960-1962 variant from the 1960-1973 logo (which is nicknamed as “Trumpetted Lion”), which is really disturbing.
NIGHTMARE for the 1960-1962 variant from the 1960-1973 logo. It sounds very sudden with the dramatic music synced to Leo’s roar, and it can scare every person in the whole world. This can also awake Eric, Stan, Kyle and Kenny when they see that logo.
Low to medium for the rest. Leo can still awake Eric, Stan, Kyle and Kenny.
Minimal for the Tom and Jerry variant. The sudden appearance of Tom the Cat after Leo is more hilarious than scary.
The scare factor is lower for those who are used to it for all logos.
Cheesy Factor (for the 1960-1962 variant from the 1960-1973 logo)Edit
The horns in the dramatic theme synchronized to the roar also don't sound right.
