Just finished watching go hi-fi although the documentary had a lot of information I felt that they spent too much time on the invention of the first cassette recorder and how the Germans invented the cassette recorder. They had to toss Hitler in there for what reason I'm not sure at that time in history Germany did have many of the modern-day inventions but to say that recordings came from Hitler was just absolutely insane. Again, they spend too much time on this topic they should have went into the first releases of Home cassette maybe different brands of cassette or cassette players or tape players they showed a few advertising commercials but not nearly as many as I thought they would. They should have went into the boom of cassette tapes and some of the bigger releases or Brands there's so many different kinds of tapes that were released around those time periods they they could have did whole segments on certain companies and Brands fill up Sony Magnavox Memorex they really didn't go into too much detail they talk about the 1920s and 1940s Hitler and then BAM they're talking about 2019 and 2020 tape sales. 50 years of history they left out. And theybspent waaay too much time talking about the pxl 2000, yes it was cool, but far from ground breaking or functional. All thebstuff they left out was the fun time when cassettes were one of the largest forms of media. Looks like a Hipster obsessed with Nazis made this. Oh how new artists are relaseing cassettes. Too bad this had LOTS of potential.
