This market was initially filled by illegal peer - to - peer file sharing technologies, and then by online retailers such as the iTunes Store and Amazon.com . This low end disruption eventually undermined the sales of physical, high - cost recordings such as records, tapes and CDs . </Td> </Tr> <Tr> <Td> Streaming video </Td> <Td> Video rental </Td> <Td> Video on demand software can run on many Internet - enabled devices . Since licensing deals between film studios and streaming providers have become standard, this has obviated the need for people to seek rentals at physically separate locations . Netflix, a dominant company in this market, was cited as a significant threat to video stores when it first expanded beyond DVD by mail offerings . The Netflix co-founders approached rental chain Blockbuster LLC in 2000 trying to sell their company . Blockbuster declined and ultimately ceased operation ten years later . </Td> </Tr> <Tr> <Td> Photography </Td> <Td> Digital photography </Td> <Td> Chemical photography </Td> <Td> Early digital cameras suffered from low picture quality and resolution and long shutter lag . Quality and resolution are no longer major issues in the 2010s and shutter lag issues have been largely resolved . The convenience of small memory cards and portable hard drives that hold hundreds or thousands of pictures, as well as the lack of the need to develop these pictures, also helped make digital cameras the market leader . Digital cameras have a high power consumption (but several lightweight battery packs can provide enough power for thousands of pictures). Cameras for classic photography are stand - alone devices . In the same manner, high - resolution digital video recording has replaced film stock, except for high - budget motion pictures and fine art . The rise of digital cameras led Eastman Kodak, one of the largest camera companies for decades, to declare bankruptcy in 2012 . Despite inventing one of the first digital cameras in 1975, Kodak remained invested in traditional film until much later . </Td> </Tr> <Tr> <Td> High speed CMOS video sensors </Td> <Td> Photographic film </Td> <Td> When first introduced, high speed CMOS sensors were less sensitive, had lower resolution, and cameras based on them had less duration (record time). The advantage of rapid setup time, editing in the camera, and nearly - instantaneous review quickly eliminated 16 mm high speed film systems . CMOS - based cameras also require less power (single phase 110 V AC and a few amps for high - performance CMOS, direct current 5V or 3.3 V and two or three amps for low - power CMOS, vs. 240 V single - or three - phase at 20 - 50 A for film cameras). Continuing advances have overtaken 35 mm film and are challenging 70 mm film applications . </Td> </Tr>
