Radio and Television made Kentucky basketball.
In the Rupp era Kentucky had two clear channel radio stations carrying UK basketball. Then in the late '50's two TV stations, WAVE in Louisville and WKYT in Lexington, basically started a UK Network that spread to many station in Kentucky and surrounding states. Long before ESPN and other "networks" I was watching the "UK Network".
In 1976 I was transferred to Florida the first time. I was back to getting radio instead of TV, except for NBC's game of the week. Then I was saved by cable TV and then in the fall of 1979 ESPN started and I was saved! 1983 I was transferred to Evansville so I could again pick up the UK Network games and with a combination of NBC, UK Network and ESPN I never missed a game. In 1986 I was transferred to Houston, TX and because of the UK Network I did not miss one game. The UK Network was on satellite so I bought one and watched every darned game. Even the games that were out of market were on satellite. I had died and gone to TV basketball heaven. I then used a satellite dish later after being transferred to Baltimore, MD and back to Jacksonville, FL.
So based on my history of "watching" UK basketball I state that the Modern Era began in 1958 with my ability to watch UK basketball on TV. I even got to watch the NCAA tourney on WAVE-TV years and years before NBC offered it.
UNC, Duke, Indiana, Kansas et.al. did not have many games on TV like UK. I know because I lived in North Carolina, Maryland, Indiana, Florida and Texas and those states were sport deserts when it came to college basketball on TV. The last Kentucky game that I have missed either on radio, TV or being there was in December 1965 when I had a chemistry test in college that I could not miss.
Sorry for hurting feelings but Kentucky had basketball on TV before any. Video tape was made available in late 1977 and I can prove how much UK was on TV because I collected the games. How did I get those games living in Maryland, Indiana, Florida and Texas? UK Network, NBC, CBS, ESPN et.al. and all used satellite for their distribution and was available anywhere in the US. Satellite TV was expensive when they first came out with it, but the dividends were great. My den was always full of UK fans and they would furnish the beer!
