That continuous name claim is disputed. From the wikipedia entry on the Phillies-
Carpenter’s first act was to try to change the team’s name to “Blue Jays.” However, “Phillies” continued to appear on the team’s jerseys. Students at Johns Hopkins University, whose teams have long been known as the Blue Jays, vehemently protested the change. They claimed that the Phillies’ attempt to use the name was an insult to their school, given the team’s reputation as a chronic loser. The experiment was dropped after only two seasons.
For two years in the 40’s the team’s owner renamed the NL Philadelphia team.
Only a hardcore baseball nut like me would even know that. LOL.
