No "Brand Central" in 1960!
Wow, how times have changed since 1960! Can you imagine Sears trying to put a catalog together today (internet notwithstanding) with Kenmore, Maytag, GE, Whirlpool, Amana, LG and Frigidaire washers?
BTW, Wisk was the only liquid laundry product I recall for many years--at least in St. Louis. P & G launched liquids called Tag and Biz (yeah, Biz!) shortly after Wisk was launched, but P & G had production problems which they really didn't get solved until Era came out in the 70s. I remember a Liquid "all," but Unilever's big push was Cold Water "all" which was introduced in St. Louis around 1964.
Dynamo was first introduced as a blue, 1/2-cup Wisk-type liquid in 1962 or 1963 (St. Louis may have been a test market). I remember their TV commercials, because Dynamo claimed it "fights dirt backwash" (early liquids apparently didn't keep dirt from washing back onto the clean clothes). George O'Hanlon, the voice of George Jetson, was the grumpy father in a series of commercials featuring a typical family (including a very large sheep dog named Siegfried who jumped on people and got them dirty, hence the need for Dynamo). In 1963, there was even a "controlled suds Dynamo powder"--which disappeared when Ajax Laundry Detergent debuted in 1964.
The 1/4-cup Dynamo debuted in 1975 ("the little blue jug is...")..."ho, ho, ho, now you know..."
