In the early days of television the shows were live or on tape. Desi Arnez pioneered the idea of putting I Love Lucy on film because the tape copies of such a show were extremely poor. It made him and Lucy very rich. Digital is quite handy but is still quite iffy as to how long it will last. I have family photographs from the 1920 that are in perfect condition. Ditto with negatives from the 1930s on.
