I think that picrelated is one of the most important pieces of information you can find on the Internet.
It's not perfect, though. A review of the image that I've found is
https://skeptics.stackexchange.com/questions/19974/are-american-media-controlled-mostly-by-jewsWhile it does use the word "problematic" in its very first line and argues that even though Jews hold key positions of the biggest media companies, it doesn't necessarily mean they influence the content in any way, among other retarded things, it still does make a few valid points. I want to remake this image myself and have it be perfectly factual, and give it an update while I'm on it, but the process is quite time-consuming.
I invite /polpol/ to help me make sure the new image does not have any mistakes; suggestions on which companies we should add to the list or remove from it are also appreciated.
If you have the time, pick a random place on the table, startpage the name in that position, and then startpage the name for any Jewish links. Valid sources include the usual big media, biographies, books, statements by the people themselves, statements by people who personally know the person in question or the person's family, participation in Jewish events, onomastics websites, etc. Invalid sources are blogs (especially politicized ones), stormfront-tier websites and other obviously crappy sources. Post the info in the thread and I'll add it to the table. I'll show examples in the next post.
