9 Jul 1982 in rolling out the film “Tron” — the first ever motion picture using computer graphics. Sci-Fi creation was released by Walt Disney and directed it Stephen Lisberger. The film tells the story of how a very inquisitive programmer Kevin Flynn, working for the largest Corporation ENCOM, manages to get inside the computer and feel the hard way all the hardships of a totalitarian regime software. The film’s budget was 17 million dollars — serious money in those days. Cash charges amounted to no less than 33 million dollars. Although some argue that the film has not been successful.
However, this is not important. As we have said, “the Throne” is the first in the history of cinema project, which involved computer graphics. Basically it is to create special effects, and renderers motorcycles and background elements. The film is a piece lasting 20 minutes that uses only computer graphics and animated characters combined with drawn. Was first presented a computer animation of the face. That is why the “Throne” is the ancestor of CGI (computer-generated imagery, images, computer-generated) in the film, without which now can not do any blockbuster.
Based on the “Throne” was released a few games, and in 2010 came the continuation called “Tron: legacy”.

July 9, 2005, the company Philips was able to record on dual layer DVD 150 GB of information. This technology was applied in near-field optical recording, the essence of which is to achieve the minimum distance between the head that produces read/write, and data carrier to 25 nm. As a result, the Philips engineers have managed as close as possible to place paths to each other, because optical media recording density depends on the focusing of the laser beam and its size, which is limited by diffraction. To reduce the spot of the laser beam by reducing the wavelength and aperture of lens (NA). Philips managed to reduce the first parameter to 450 nm, and the second to 1.5 NA. For comparison: a standard CD (700 MB) works with 780-nm laser and the aperture of the 0.45 NA; ordinary single-layer DVD (4.7 GB) can boast of 650 nm and 0.6 NA; Blu-Ray (25 GB) has a wavelength of 405 nm and 0.85 NA.
Why, over time, to a such DVDs? Everything is quite prosaic. First, the technology was expensive to manufacture. Secondly, as time has shown, the film industry (the main consumer optical media) in the end I chose the Blu-Ray standard (again for economic reasons).

9 Jul 2014 Alcatel-Lucent (Bell Labs) has set a speed record for data transmission over telephone lines — 10 GB/s. This was demonstrated technology XG-FAST, which provides for available networks based on copper cables symmetrical ultra broadband access with a speed of 1 Gbit/s Is two times faster than the development of G. fast, which was certified only in 2015. It should be clarified that 1 Gbps was achieved with a wire length of 70 m, and 10 Gbps with a cable length of 30 metres.
