Pay Television (Pay-TV)
(see also Cable Television)

The concept of pay-TV first emerged in the 1960s as a way for viewers to access premium programming that was not available on broadcast television. The first pay-TV service, called Subscription Television (STV), was launched in Pennsylvania in 1963.

STV was a closed-circuit system that used a set-top box to scramble and unscramble the signal, which prevented non-subscribers from accessing the premium channels. The service offered movies, sports, and other programming for a monthly fee, and it was initially successful in attracting subscribers.

However, pay-TV faced several challenges in the 1960s and 1970s, including technical issues with the set-top boxes, high subscription costs, and resistance from broadcasters and regulators who were concerned about the impact of pay-TV on the traditional broadcast model.

As a result, pay-TV did not become a widespread phenomenon until the 1980s, when technological advancements and regulatory changes made it more feasible and attractive to consumers.

In the 1980s and 1990s, cable television became a major player in the media landscape, with the consolidation of the industry leading to the emergence of large media conglomerates like Comcast, Time Warner, and Viacom. The growth of the internet and the emergence of new digital technologies have also had a significant impact on the cable industry, with many cable providers now offering high-speed internet and other digital services alongside traditional cable television.

AI Technical Trustability Update

While working on an update to my RF Cafe Espresso Engineering Workbook project to add a couple calculators about FM sidebands (available soon). The good news is that AI provided excellent VBA code to generate a set of Bessel function plots. The bad news is when I asked for a table showing at which modulation indices sidebands 0 (carrier) through 5 vanish, none of the agents got it right. Some were really bad. The AI agents typically explain their reason and method correctly, then go on to produces bad results. Even after pointing out errors, subsequent results are still wrong. I do a lot of AI work and see this often, even with subscribing to professional versions. I ultimately generated the table myself. There is going to be a lot of inaccurate information out there based on unverified AI queries, so beware.
