Historical 'Surprises' Comparisons

Does anyone know of a site that consolidates historical surprises of a company and how they compare to related companies' historical surprises? Any suggestions would be greatly appreciated. Thanks.
 
I have quarterly earnings surprises of every company in the S&P500 and R2000 indexes as far back as 25 years ago, with no survivor bias.

interesting. Did you collect it yourself or you subscribe to some data service? Thanks.
 
data was collected from different official sources for our clients, and we paid for the data.

It was mainly used for a multi-billions fund until 2009, when the fund collapsed.
