Of course, the media behind this also has a certain relationship. There were many American inventors at that time, but only Edison was the most dazzling star. At that time, Tesla was still a young man and only worked as an assistant for Edison, so it was normal for him to be forgotten by media reporters.
His obscurity was partly due to the ignorance of the news media at that time, but more due to Edison. Although Tesla worked with Edison when he was young, he was successful when he was young because of Edison's support. But Edison often criticized and laughed at many of Tesla's ideas as "unrealistic", and secretly stole Tesla's patents, thus gradually achieving his own business empire.
In any case, we still have to understand that although Edison tried his best to deal with Tesla, in fact, a large part of Tesla's early development benefited from Edison's funding. From this perspective, Tesla is also kind to Edison, so no matter how Edison bullied him, Tesla just smiled. After all, fame and fortune are not important to him, and his greatest pursuit in life is to benefit all mankind.
