It very much depends about which country you're asking. I am Dutch, in those days we didn't have advertis*m*nts in programs. Only short blocks before and after the news. 'American' in-program advertis*m*nts and 24/7 broadcasting came much later, mid or late 70's, if I recall correctly.
As far as I know in 1969 in-program advertis*m*nts, certainly for a major event like that, were not done. It would probably have caused an outcry back then. We have digressed/progressed (pick your choice) a lot since then.
