File:Layout engine usage share.png A rough estimation of usage share of layout engines/web browsers
This article aims to be an unbiased historical record for the usage share of web browsers (but ideally layout engines , as it is what matters), based on statistics and articles published by well-known websites . One of the use of such statistics is to create a graph that roughly represents the browser wars . This also serves as a reference for the various web browser articles.
This article is not all-inclusive or necessarily up-to-date. It should be noted that while the record was achieved unbiased, the record itselfs may not totally reflect the fact, i.e. there may be certain degrees of overestimation and underestimation. It also does not account for the regional differences in market share.
