blow by blow

blow by blow idiom
Described in minute detail, as in Tell me about last night's party, blow by blow. This term originated in radio broadcasts during the 1930s, in which the sportscaster gave a detailed account of each punch struck in a boxing match. It soon was transferred to a detailed account of anything at all.
