Re: Batman - The 1940s Serials
And I've been saying for years that the Batsignal is an obsolete notion; by now Commissioner Gordon should be doing something like sending Batman a tweet.
No doubt this is so for the purpose of summoning Batman, but authors have claimed that the signal has additional psychological roles, from intimidating criminals to boosting the morale of the city population at large.
