It was also one of the only (that I can remember aside from maybe SUSE - maaaybe Slack?) actually putting their distro in stores back in the 90s. I was a middle schooler and used Christmas money to buy RedHat at Best Buy (I had no idea what I was doing) because I thought it was the distro to get. I can’t remember a single other distro more synonymously associated with Linux than RedHat because they were marketed hard and were widely available for purchase which I’m guessing made them at least appear more legitimate to new Linux consumer and business adopters.
