<s>[INST] is it true that thomas edison stole the light bulb idea from nikola tesla? if not why do so many people think so? [/INST] It is not true. It is correct that Thomas Edison wasn't the first to think of or invent an electric lamp, but the one to make the light bulb more commercially viable and the first to successfully bring it to market. However, Nikola Tesla was not involved in the lightbulb.
Despite his contribution, what Edison actually did in history still contrasts strongly with his well-known inventor stories and makes many people consider him as an liar. Meanwhile, Tesla's less-known innovations in electricity distribution, radio, wireless power, etc. together with his "mad-scientist" rumors makes him the "forgotten selfless inventor". Though there is no evidence that they deeply hate each other, their ideolgies did clash fiercely in the War of the Currents between the Westinghouse and Edison companies. The idea of a feud between them involving stealing patents, lies, and sabotages also began to get popularity in literature, movies, games, .etc. Therefore, it is very common that people will consider contributions related to Edison to be stolen from Tesla.</s>\ <s>[INST] What popular media has portrayed Edison and Tesla as rivals or enemies involved in a feud, and what inspired these portrays? [/INST] The rivalry of Thomas Edison and Nikola Tesla is a well known fact and therefore has been depicted in a variety of media. The rivalry is based a series of historical  events which is nowadays known as "War of the Currents." During the late 19th and early 20th centuries, the two inventors and their respective companies were competing each other with their own electrical power transmission systems. Edison advocated direct current (DC) while Tesla, along with George Westinghouse, promoted alternating current (AC). Their competition with these systems and the inventors became highly famous, since their innovative impact on society and the electrical industry is considered to be of an immense magnitude. Their historical relevance has lead to a large variety of portrayals, also in popular media.
See a some examples regarding popular media on this topic:

- **The Prestige** (2006) - Directed by Christopher Nolan. Mainly focusing on the story of Tesla. Edison does not have a significant role but their feud is mentioned.
- **The Current War** (2017) - Biographical drama; directed by Alfonso Gomez-Rejon. Starring Benedict Cumberbatch as Edison and Nicholas Hoult as Tesla. Depicts their intense rivalry and how both strive for dominance in the emerging electrical industry.
- **Drunk History** (2013-2019) - TV show by Comedy Central. There is one episode of Season 1 which is called "Tesla & Edison". It humorously tells the story of Tesla, portrayed by John C. Reilly, and Edison, played by Crispin Glover.

Also various books and graphic novels illustrate the rivalry between Edison and Tesla. Instances are "**Tesla: Man Out of Time**" by Margaret Cheney, "**The Last Days of Night**" by Graham Moore, and "**The Five Fists of Science**" by Matt Fraction and Steven Sanders.</s>\ <s>[INST] Who was the better inventor?
