Green

All of a sudden, green is becoming the most favorite color. The NBC logo designed in 1976 (from a Nebraska PBS station's logo) has changed from a multicolored logo (rainbow?) to a green-colored logo. Just noticed this as I was watching the Sunday Night NFL game. Green to represent the ecology? Green to represent the Fighting Irish? Sorry, NBC! You may be broadcasting the Notre Dame home games; however, this is the wrong year to support their color. Or are you going to be merging with BP?
You had a very unique multicolored logo. Unlike most logos that are in various hues of red, blue, or maybe yellow. Why the change?
