Git has unfortunately-named nevertheless handy tool for exploring historical file data -- git blame. There's an alternative GUI implementation for Mercurial thg annotate, a part of Tortoise Hg suite.

Annotate tool works exactly the same as blame, just specify a file name i.e. thg annotate and a window will pop up with revision list, diff and annotate options.

Right-clicking on diff window and selecting Annotate Options brings up possible annotation selection that for some reason aren't selected by default: 'Show Author', 'Show Date' and 'Show Revision'.
