In the early 1980s, vendors of the desktop scanners had their own scanning format and there was no standard format for scanning images. Keeping in view this requirement, efforts were made to develop a common scanning format for desktop scanners. It was due to this reason TIFF image format was developed in the mid of 1980s.
At that time desktop scanners used to scan documents in binary format. The scanned pixel could have only 0 or 1 as their values; hence the initial TIFF was in the binary form. With the passage of time, technology evolved and scanners became more sophisticated and powerful and started to accommodate grey scale images as well. Finally color images were also stored in TIFF format. Today TIFF is capable of storing high depth color images of several types. No major update to the TIFF file format has been released after 1992.
