Most of the credit for the popularity of Batman gadgets that one sees in toyshops all over the country goes to the television series of the 1960s. The comic strips and the movies did very little to popularize these gadgets that Batman uses to fight criminals.
As the story goes, Batman developed a dislike for guns as his father was killed with one. Batman is not endowed with any superhuman powers, so the superhero depends more on gadgets rather than anything else.
Ranging from Batrope and Batrang to the exciting Batmobile, all Batman gadgets are black in color with the Batman logo imprinted on them. The handy gadgets lie in the Utility Belts of Batman and Robin and all that they have to do is to dig in to it and use any one of them as warranted by the situation. The bigger ones are parked in the Bat Cave.
The Batrope is used for climbing large skyscrapers. The Batrang is shaped as a boomerang, used as a weapon and hurled at villains to disable them. For mobility on road, air and sea, Batman uses Batmobile, Batboat, Batcycle, and Batwing.
The old tales of Batman as narrated in DC comics were relevant for the times that they were created for. They used gadgets which now seem antiquated. Keeping in tune with the change in technological environment, Batman gadgets too have changed. The TV series and the movie played a significant role in the emergence of new Batman gadgets that he uses to curb crime. Tim Burrton's movie equipped the Batmobile with grenades and machine guns, and the Batwing with missiles and rockets, which is actually very unlike Batman.
The stories in the TV series retained the original appeal and introduced new gadgets in the shape of a Bar Radar, Bat Cuffs, and even a Bat Spray to immobilize sharks. Over time, Batmobile, a black shining car with huge tail fins, capable of incredible speeds has remained the most fascinating gadget. The appeal of the Batmobile is so strong and emphatic, that even adults are enthralled by the vehicle.
Far removed from the current day icons of media and mobile games, Batman uses minimum of violence and has a positive message for children of all ages. Batman and Batman gadgets have retained their popularity, having lived and evolved over more than five decades. Batman is a cultural icon of the country with a much needed appeal of victory of the good over the evil with non-violence. That is what explains the sustained popularity of Batman and the continuing sale of gadgets that he uses in his campaign against crime.
