Gaps between inventions and commercial availability

There have been several significant gaps between the invention of a new technology or product and its commercial availability. Here are some notable examples:

1. Television: The technology for television was invented in the late 1800s, but it was not until the 1930s that it became commercially available to the public.
2. Personal Computers: The first personal computers were developed in the 1960s, but it was not until the 1980s that they became widely available for home use.
3. Electric Cars: Electric cars were first developed in the late 1800s, but it was not until the 2000s that they became commercially viable for mass production and use.
4. Virtual Reality: The concept of virtual reality was developed in the 1960s, but it was not until the 2010s that the technology became commercially available and affordable for consumers.
5. Artificial Intelligence: The concept of artificial intelligence dates back to the 1950s, but it was not until the 2010s that the technology became advanced enough for widespread commercial use in industries such as healthcare, finance, and transportation.
6. 3D Printing: The technology for 3D printing was developed in the 1980s, but it was not until the 2010s that the technology became affordable and accessible for consumers and small businesses.
7. Internet: The precursor to the internet, ARPANET, was created in the 1960s, but it was not until the 1990s that the World Wide Web and modern internet as we know it became widely available to the public.
8. Self-driving cars: The concept of self-driving cars has been around since the 1920s, but it was not until the 2010s that the technology became advanced enough for testing and some limited commercial availability.
9. Augmented Reality: The concept of augmented reality (AR) dates back to the 1960s, but it was not until the 2010s that AR technology became advanced enough for commercial use in applications such as gaming and advertising.
10. Smartphones: The concept of a handheld mobile phone dates back to the 1970s, but it was not until the early 2000s that the first smartphones were introduced, and it took several more years for them to become widespread and affordable for consumers,
    

Overall, the time gap between invention and commercial availability can vary widely depending on factors such as technological advancements, market demand, and regulatory and financial considerations.
