Batman (comic book)
Though the "Batman" comic book was initially launched as a quarterly publication, it later became a bimonthly series through the late 1950s, after which it became a monthly publication and has remained so since. In September 2011, The New 52 rebooted DC's continuity. In this new timeline, the original "Batman" series ended and was relaunched with a new first issue.
