Whakaotihia te rerenga e whai ake nei: I mahi a Brockman hei kaiwhakataetae hakinakina i runga i te WXLW, WIRE me te mahi hei kaiwhakahaere hakinakina i WLWI (i tenei wa ko WTHR) i Indianapolis, Indiana. Mai i te tau 1964-
I te tau 1970, i whakarewahia e ia nga whakaaturanga pouaka whakaata a te MCA mo te Indianapolis 500. I mahi ia i runga i te "Wide World of Sports" a ABC, a, i whakarewahia e ia te whakaaturanga o te 1965 Indianapolis 500. Ko ia hoki tetahi o nga kaitohutohu tono 3 mo te tono a Bobby Unser mo tana whiu 1-huringa whai muri i te 1981 Indianapolis 500. Ko Brockman anake te kaiwhakawa ki te pupuri i te whiu a USAC, ahakoa kaore ia i whakaae ki te whakatau a te roopu kia kaua e whiua te kaihauturu a Mario Andretti mo te takahi rite.
