The real question is: would TO ads provide enough brand recognition among professionals (your consumers) to justify the expense? Dubious, IMO.If you think TO readers are a target market, your effort would be better spent formulating ideas for press releases to entice TO to run a story about you.The old adage is apt: Advertising, you pay for; Publicity, you pray for.Caveat: Having never dealt with TO, I don't know them or how they operate. However, many publications won't even consider running a story unless you're a star or an advertiser. Or spectacularly unique.
