Tl;Dr: Mostly with excitement, although it was delayed for much of the country.

Let me back up a sec. Broadcasting radio generally was met with concern over what was kind of its magical quality - ethereal, literally - that in some ways, affected how early communications law was developed because broadcasting entered the home univited. The concerning aspect there was that any obscene or violent content could not be stopped - could not be protected against - so when the government licensed stations to have control over the spectrum, they had a duty to serve the public's best interest meaning, in part, to be a good guest. TV's big public debut was at the world's fair in 1939, and those who could afford early commercial television sets like the RCA 630 and lived in one of the major metropolitan areas were the first adopters. But new stations popping up everywhere were deluging the FCC for requests for licenses, and the FCC was struggling to keep up while trying to maintain a consistency in protocols and technologies for the new medium - particularly with standardizing a colorcasting system. So they issued a licensing freeze in 1948 that was meant to last for about 6 months but dragged on until 1952. That meant much of the American public, particularly in broad swaths in the Midwest, didn't have Television pumping over their airwaves and thus had some time to adjust to the idea of the medium before it came to visit. Manufacturers also had time to hone the technology of TV sets that began to make them more affordable for middle class folks whose tastes in content, in turn changed the kind of programming the 60s offered. For recommended reading, I recommend Lynn Spigel's (PhD) MAKE ROOM FOR TV, which discusses the technology of TV and the way the industry marketed it to suburban housewives. One interesting bit there was how magazines were teaching women how to incorporate the gigantic appliance (might as well be a refrigerator!) into the flow of their exquisitely designed ranch house living rooms, and how magazines also instructed women how to incorporate TV into the culture of their lives as a structuring part of their day. The soap opera, for instance, was adapted in large part to sell TVs to women, and portable TVs like Philco's Transitone and Seventeener were created in part to follow women around as they did housework.
