One of the first commercial products I launched on my own behalf was Friday, a personal Information Manager that ran under DOS as a TSR (Terminate and Stay Resident) utility which you could call up at a keypress whenever you needed it. It offered full appointment sheduling with alarms, a contacts database with which you could dial people directly (if you had a modem) using a single keypress, a 200 year calendar and more. I marketed it as Try before you Buy Shareware on bulletin boards, magazine cover disks and very little elsewhere. Here is one of the few print ads I placed. I think the copy was OK but the designer seriously let me down - this ad taught me to never trust a designer's word about something without seeing it for yourself.
