In my own household, my parents didn't get their first color TV until probably 1976, and it was a used TV. I don't remember the brand, but I only know it was a tube TV. My family borrowed TV's from family for a few years and alternated between color & black & white. One color TV we had was a Magnavox Solid State made in 1973 or 1974, my parents bought used. That lasted a couple of years. Don't know what went wrong with it, but it caught on fire in 1985, and we didn't have another color TV again until after my dad's death, & my mom bought a new Sanyo TV from Service Merchandise. So between 1985 & 1991, we had black & white Montgomery Ward tube TV, a Zenith black & white tube TV given to me, and a 9 inch Portland black & white TV my dad used while on the road (he was a truck driver).
My maternal grandmother didn't officially buy a color TV, but my Aunt Nancy bought one for the household, & she bought an RCA 19" Solid State color TV in 1971 or 1972. Since then, she bought a 25" RCA color TV with remote in 1985, and lasted 6 years. Then she got a 25" Mitsubishi TV, and lasted 5 years. Then she got another RCA and lasted I believe 6 years. Then she got a Philips, and only lasted 2 years. She went back to RCA, and so far, it's held up for 6 years. My grandma has had her TV's on a lot. My Aunt Nancy has bought all the color TV's. The only TV's my Grandma bought were the few black & white TV's she owned, including a Panasonic 19" & 12" Zenith she got from the now defunct Mays Family Center. She doesn't have the Panasonic TV, but still has the Zenith one.
My paternal grandmother didn't get her first color TV until 1985, all because my grandpa refused to buy one while he was alive. As long as the TV he had worked, he didn't care. My grandpa sisn't get his first TV with a UHF tuner built-in until 1973, and that was a Sears black & white console. After my grandpa died, my grandma went to Sears & bought a Sears color TV. I don't remember how long that lasted, but it lasted a few years. Then she got an RCA console from Rent-A-Center, and she had that TV repaired a lot. It still worked when she left Indiana in 2000. I have no clue as to what she has now, if she even has one. She lives with my Aunt Brenda & Uncle Vince, and I haven't visited them in Arizona yet.
As for myself, only 36 (37 at the end of this month), my first color TV I bought with my own money was a used GE 15" color TV (1994). That TV was ok, but it didn't last long. I only paid $15 for it. It had a good tuner in it, but the picture squinted after a couple of hours of use. I went to see if it could be fixed, and found out that it would have been difficult to get it fixed. It needed about 5 tubes (TV had 8, which didn't include the picture tube), and 3 of the tubes weren't available at the repair shop, and all tubes were discontinued. So I had to junk that TV. It was too bad because it was otherwise a good TV. The UHF tuner didn't lock, as it was one of the earliest UHF tuners. The rabbit ears & loop antenna were sufficient enough that I didn't need the outdoor antenna with that TV. I later got an RCA 14" color TV, and that was ok, except that there was a problem with the tuner on it. Again, I got that TV in 1994 The picture went all over the place. The repair shop didn't want to order the tuner for it, as it was half the cost of what I paid for the TV. So the repair shop gave me a replacement and got a Philco color TV (made before Philips Electronics bought the company from GTE). That TV I also got in 1994. When I moved, I bought a 20" RCA TV with remote, and that lasted 9 years. While it still worked in 2004, I threw it out after parts of the picture tube broke, and a third of the left side was mostly red, the center thirs was normal, while the right third was mostly green. Since neither Kmart nor Walmart had HDTV's available locally in 2003, I was forced to buy an analog TV, and got a 24" RCA TV. I'm currently using that TV with my Magnavox DTV converter box. While the TV was put on layaway at Kmart in 2003, I got it out an used it for the first time in 2004. Kmart had it on sale, and that was why I got it. It was ironic that Kmart had it cheaper than Walmart. I haven't decided what my first flat panel TV will be. I only know that I won't be getting an RCA, since RCA TV's are hard to find locally. Stores in my area are overall selling a lot of Magnavox, Philips, Vizio, Samsung, LG (this brand practically replaced Zenith in most of the country, after LG bought Zenith), & Sanyo. LED TV's are slowly replacing LCD TV's, & I expect my next TV to be an LED. I just have to decide on brand. I've been used to RCA, but I most likely will have to move onto a different brand, now that RCA is next to impossible to find locally, and not sure I want to buy online.
