As you've no doubt read, the inventors of the CCD- W. S. Boyle and G. G. Amelio- were just awarded the Nobel Prize in Physics. As with any development, nothing happens in a vacuum, and the history of digital photography owes a lot to what laid the foundation for this invention, and what followed it. I've done some pretty geeky work before on the timeline of digital photography, but this award has pushed me to greater heights of geekdom.
Take a trip down Memory Lane- starting with the development of the Integrated Circuit- the IC, in 1960, that would replace the vacuum tube and start the whole revolution. I even found the point at which Moore's Law was first formed. Supremely geeky stuff!

Moore's law was later amended to, "the number of components per IC doubles every 18 months". Moore's law holds true to this day.

Some fairly random notes:
From about 1960 on to, oh, say 1970, semiconductors, integrated circuits, even just the idea of making silicon wafers was new stuff.
Moore’s Law is a very interesting early observation which not only comments on the pace of IC development and the miniaturization of components in electronics, but it’s been used to comment on the pace of technology itself. All from a paper titled “Cramming more components into Integrated Circuits”.
Serious image sensor work, both in CCD and CMOS technology started in the mid-‘60s, and the first camera was proposed in 1975. From 1970 to 1980 or so, there were some serious developments in the physical design of the sensor. The Interline CCD was the most common design for cameras ca. 2001, it was developed in ’73.
The mid-to-late ‘80s saw start of the development of actual digital cameras. We get the Tessara, the Leaf DCB, the Sony Mavica… in the ‘90s we’re getting consumer friendly cameras like the Logitech Dycam, Apple’s Quicktake 100, and the Casio QV-10, along with several Kodak products.
In the late ‘90’s the development of Compact Flash memory and on-camera LCDs moved the cameras into position to be a true rival to a hand-held film camera.
The release of the Nikon D1 in 1999 was the first true, single-manufacturer DSLR camera offered, and may commercial photographers’ first foray into digital photography for commercial work. A very short four years later, with the Digital Rebel, Canon opened digital photography with SLR system-based features up to the consumer market. That year, as well, saw digital camera sales surpass film camera sales for the first time in history. Nikon, Canon and Kodak soon ceased production of all film cameras- Kodak in 2004, Nikon and Canon in 2006.
