As with almost anything we discuss, you could define your terms any number of ways. But to whatever degree I'm still acknowledged as an expert in this field (as I said on my old website "everybody ought to be an expert about something"), I'm digging the idea of Shop 'Til You Drop being the best answer for this.
In terms of what some of us still consider a "traditional" game show run (daily network show) the three longest-running shows without a home game go all the way back to the fifties: Queen For A Day, The Big Payoff and Who Do You Trust. YMMV, however, on whether any or all of them are traditional game shows.
