This is your sign to upgrade your old Blu-ray discs now

It might not seem like it, but the Blu-ray format has been around for a few decades now. While 4K Blu-ray is the next iteration of the format, it hasn’t stopped Blu-ray or even DVD from still being big sellers. In fact, those formats are more popular than 4K, but it doesn’t mean they’re better. DVDs are by far the lowest quality of the three, which is ironic because they’re also the best-selling. Money talks, I suppose.
