decent idea at the time, doomed to fail
Way back when SPOT was unveiled it was an interesting idea. But in my opinion the monthly subscription charges was what made it a non-starter. (My how things have changed, now a smartphone probably eats up 3x that in a data plan subscription.)
Back then pagers were still pretty popular, too so maybe nobody needed them for that reason either.
Neat technology, had to cost a small fortune to get nationwide radio coverage, but not worth the subscription.
