Do you/did you usually tend to stick to one brand for your main sets?

Growing up in the 60's and 70's, I remember that our family usually stuck to RCA's (and the occaisional Zenith) for our sets. I was wondering if most of the people here who had multiple sets in the house stuck to one brand, or had multiple brands. The first sets I remember us having in the house were a circa 1960 (the year I was born) RCA 21" console, then a circa 1963 GE 11" portable which my brother and I had in our bedroom (a neighbour worked for the ad company GE used in Canada, and got it for us at a good price). Other than that, when a set conked out, we usually went for RCA, except for our first color set, a Zenith from 1969--that set lasted for years!
Sorry for rambling, but I was just wondering if most of you (or your family) had a "brand loyalty"--something which I doubt most people have now!
