Wolfman and interior penciler Pat Broderick, before having his origin detailed in Batman: A Lonely Place of Dying, a crossover story between the ongoing series Batman and New Titans, written by Wolfman and penciled by George Pérez and Jim Aparo (the latter with inks by Mike DeCarlo), in which he first introduced himself to Dick Grayson and impressed the former Robin with his skills. This led Grayson and later Alfred Pennyworth, Bruce Wayne's butler, to support Tim's request to be Batman's new partner. Not wanting to make the same mistake as he did with Jason Todd, Batman had Tim endure an intensive period of training that was never given to his predecessors. As such, Tim remained a non-superhero supporting character for the first year of his regular appearances in the Batman title, mainly operating in the Batcave. The ensuing Tim Drake storylines, authored by the late Alan Grant and penciled by Norm Breyfogle, coupled with the 1989 release of Burton's Batman, spurred sales of both Batman and Detective Comics. For the latter title, Grant attested in 2007 that "when the Batman movie came out, the sales went up, if I recall correctly, from around 75,000 to about 675,000." 1989-90 was indeed the "Year of the Bat:" Capital and Diamond City Distributors reported that the Year One-inspired Batman: Legends of the Dark Knight dominated four out of the five spots for preorders (not total sales and second printings). The only exception was the third preorder spot, snagged by Batman #442, the conclusion to Tim Drake's "A Lonely Place of Dying" storyline. The "Year of the Bat" continued into the first half of 1990. Preorders for Batman and Detective Comics issues featuring a revived Joker and Penguin began to compete with, and even edged out, the last three parts of Grant Morrison's and Klaus Janson's Gothic storyline in Legends. Todd McFarlane's Spider-Man arrived in the second half of 1990, inaugurating six months of Spidermania (or Mcfarlamania, depending on the reader). DC closed out 1990 with vendors under-ordering issues, prompting the publisher to push Batman #457 and the first part of the Robin mini-series into second and then third printings. The next year, 1991, witnessed the ascension of Chris Claremont's, Jim Lee's, and Scott Williams's X-Men against Magneto, as well as Fabian Nicieza's and Rob Liefeld's X-Force, into the top of the preorder rankings. The only exception to this X-mania was, again, Tim
