There were already color movies in the 1950s and very good color movies. Like North by Northwest to use as an example, but color TV really didn’t have much of an impact at all until the late 1960s or so. Which is why this press conference by President Dwight Eisenhower is such a big deal. Because millions of Americans were getting to see something they never saw before most likely in 1958 and something that wouldn’t become common in TV until the early 1970s.
