Short history:
The Shiller PE ratio was developed by professor Robert “Bob” Shiller and popularized during the Dotcom Bubble in the late 90s when he argued that equities were highly overvalued.
The Shiller PE is a variant of the popular price to earning ratio (PE-ratio) and is calculated by dividing the current price of a stock by its average inflation adjusted earning over the last 10 years.
