My Wikipedia Goal edit

Collecting and restoring "Dead Technology" is a disappearing skill but there are many people wanting to have the "retro" look. My goal in Wikipedia is to bring in radio and television historical articles of people, business and technology to Wikipedia and using it to link readers to other sites to expand their knowledge and maybe try to save some "dead technology". The invention of radio and television are considered one of the greatest inventions of the 20th century. It won't be long when the people, businesses and the actual products of these great inventions will be forgotten. Wikipedia would be a nice place to keep those achievements alive.
