In short, because it takes far less resources and skill to create a professional quality video these days. Advances in technology have made the tools required for doing so accessible to (almost) everyone. I came into web development from the film industry. We used to work with a lot of large ad agencies, mostly on national and international broadcast commercial packages. When I first started in the industry, shooting a commercial meant hiring a large production crew. Shooting 35mm film was still the norm, but over time producers became more open to trying HD video. Despite being cheaper than 35mm, shooting HD was still a large affair with many moving cogs. It wasn't uncommon to have to seek out and find specialized service providers just to have access to the equipment needed, even though we were one of the biggest and well-equipped post houses in Chicago. The thing is, over a period of just a few years, things within the industry radically shifted. The prosumer market began to catch up. Suddenly we had access to high-def cameras that cost nearly as much to purchase as the former technologies cost to rent just a few years prior. We started to get requests from agencies to actually shoot ads ourselves to save costs. Our coloring facilities, which used to take up two rooms of our office, shrank to the size of a desktop console. Our offline editors began to be able to add complex graphic work without the aid of our highly skilled online editing team. It simply amazes me when I walk into a post-production facility these days. What used to be rooms full of bulky equipment and stacks of film is now, quite often, nothing more than a few little desktop computers. So to return to your question... technology is no longer the barrier to creating high quality videos. The only real barrier is creativity- what you can do with all that potential at your fingertips.
