The use of a favicon seems to be an interesting innovation. It is essentially the visual identification of a website for web browsers. In researching this topic I recognized how many formats they can be in ICO’s, PNG’s, JPEG’s and GIF’s. What I found to be interesting is that Internet Explorer does not support any type of file format except an ICO. What really puzzles me about this situation is that even after the introduction of several other web browsers, almost a quarter of web users still utilize Internet Explorer.  Another topic of interest in favicons was how the iOS operating system utilizes a custom icon slot that allows the device to automatically save a sample of the web page if a favicon is not present. The question remains in light of this development, will favicons even be necessary in the developer’s world?
