| 1964 | Ampex introduces the VR-2000 high-band videotape recorder, the first ever to be capable of the color fidelity required for high-quality color broadcasting. |
| 1967 | ABC uses the Ampex HS-100 disk recorder for playback of slow-motion downhill skiing on World Series of Skiing in Vail, Colorado. Thus begins the use of slow motion instant replay in sporting events. |
| 1967 | Ampex introduces the RG memory. It is a medium capacity memory with an access time of 350 nanoseconds (less than half of one millionth of a second) and expandable from medium to very large capacity (up to 5,000,000 bits) by adding memory modules. |
| 1967 | The introduction of the Ampex VR-3000 revolutionizes video recording |

| 1969 | Ampex introduces the Videofile® system, used by Scotland Yard for the electronic storage and retrieval of fingerprints. |
| 1970 | Ampex introduces the ACR-25, the first automated robotic library system for the recording and playback of television commercials. |
| 1970 | Ampex introduces TBM (TeraBit Memory), a 2-inch transverse tape-based online digital storage system for high-performance computing applications. |
| 1972 | The first TBM delivered reaches a never-before-achieved 3 trillion-bit capacity. |
| 1974 | Ampex introduces the AVR-2, the first modular quadruplex recorder/reproducer for professional broadcasters. It requires one-half to one-third the operating space required by other quad machines. |
| 1976 | Ampex introduces the VPR-1, helical scan, 1-inch videotape recorder. The VPR-1's successor, the Type C VPR-2 (1978), becomes the industry standard for video recording. |
| 1977 | Ampex introduces the AST® process, the first automated scan tracking for variable speed effects, making slow motion possible directly from tape for the first time. |
| 1977 | Ampex introduces Electronic Still Store (ESS?) which allows producers to store digital video images for later editing and broadcast. |
| 1977 | Ampex introduces the HBR-3000, the first high-bit rate, high-density magnetic recorder for logging and storage of electromagnetic data. |
| 1978 | The Ampex Video Art (AVA?) video graphics system is used by artist Leroy Nieman on air during Super Bowl XII. AVA, the first video paint system, allows the graphic artist, using an electronic pen, to illustrate in a new medium, video. This innovation paved the way for today's high quality electronic graphics, such as those used in video games. |
| 1981 | Ampex introduces the ADO® system, which creates digital special effects, allowing rotation and perspective of video images. This changed forever the way television material would be manipulated and created. |
| 1983 | Ampex introduces the DCRS digital cassette recorder, offering compact cassette storage with the equivalent of 16 digital, 14 inch, 8 DDR instrumentation reels on one cassette. |
| 1983 | Partial-response maximum-likelihood (PRML) data decoding technology has its first use in Ampex's DCRsi? recorders. This technology is now commonly used in high performance computer disk drives and other high density magnetic data storage devices. |
| 1988 | Ampex introduces D-2, the first composite digital video recording format. |
| 1991 | Ampex obtains patent for keepered media, which adds a soft magnetic layer to magnetic recording media, increasing the resulting recording capacity. |
| 1992 | Ampex introduces its DCT® products, the first digital component post-production system using digital image compression technology to produce unsurpassed quality images. The system includes the finest videotape recorder ever made, the DCT 1700d. |
| 1992 | Ampex introduces its DST® products, high-performance computer mass data storage systems able to store half the contents of the Library of Congress in 21 square feet of floor space. |
| 1995 | Ampex introduces the DIS? 120i and DIS 160i dual port, data/instrumentation recorders, making it possible for the first time to capture real time instrumentation data and then utilize the same recorder to process the data in a computer environment through its second port using SCSI-2 protocol. |
| 1996 | Ampex introduces the new double density DST data storage product line, offering the highest capacity data storage system in the industry. The DST 812 robotic library can now store 12.8 terabytes of data, the entire Library of Congress, in 21 square feet of floor space. |
| 1997 | Ampex introduces the DST 712 Automated Cartridge Library System capable of storing up to 5.8 terabytes with an aggregate data transfer rate of up to 40MB/sec. |
