It would depend upon usage, data density on tape, and storage aspects. ==========================
Magnetic tapes stored under archival conditions (National Archives and
Records Administration example) generally have a lifespan of about 10
to 50 years before exhibiting difficult to handle decay.

On Youtube, some of those old time videos (late 1950s & onward) were
taped based. This may be an exmple below, and if person who posted it
was contacted, he could explain more about these videos.
Dorothy Collins - Wayward Wind (1956)

Note - First consumer color TV sets were available March 1954, but
even in 1956, few stations would have been broadcasting in color part
time. So, I can't say for sure if above video was recorded in film or
color.

When did TV stations start using video tape?
RCA-owned NBC first used it on The Jonathan Winters Show on October
23, 1956, when a prerecorded song sequence by Dorothy Collins in color
was included in the otherwise live television program.
