Today the University of Illinois announced that they will be returning to the use of a single logo, the orange block "I" that has been used for much of it's history. In 1997, nonathletic units began using the column "I". That will now be phased out in favor of a singular block "I" logo.
Chancellor Robert J. Jones is doing this in an effort to strengthen the Illinois brand. Is it a waste of money? A smart marketing decision? Can't say I have huge feelings on it, but I don't have any column "I" letterhead, nor do I have to go around and change all the signs on campus.
