A more accurate approach that some take is to state, "As advertised on/in."
You've also got to make certain the terms and conditions of the advertising contract. Some contracts will have clauses such as:
"Further, Advertiser hereby agrees not to use the phrase "As seen on ________", or similar statements, in any promotional or advertising material it creates or on its website." *
*Disclaimer: Consult your own attorney to help you and read the small fucking print.
