In 1991, a similar chain known as Learningsmith began operating. Learningsmith had similar connections to public broadcasting elsewhere; Boston's WGBH-TV was a backer, and it also was allied with WNET in New York, WETA-TV in Washington, and WCNY-TV in Syracuse, New York. The chain approached KCET about opening stores and receiving royalties, but the station was more interested in creating its own concept that it would own. Leonard Straus, former chairman of Thrifty Drug and a member of the board of KCET, had suggested the idea of starting an educational materials store. Straus brought in Lakeshore Learning, and the two formulated the concept for the chain. Public television stations would provide community goodwill and a built-in shopper base; Lakeshore supplied merchandising and warehouse services; and Riordan, Lewis & Haden provided the venture capital.
As Learningsmith backed off from its previous affiliations with public television and underwent an internal restructuring, two of the large PBS member stations that worked with it started Stores of Knowledge: in October 1996, WNET opened its first unit in the Garden State Plaza, and WETA partnered with the chain to start the first of four units in the Washington, D.C., area in April 1997. There were also two notable holdouts. SOK expanded into the Seattle area even though it was unsuccessful on two occasions to encourage KCTS-TV there to participate; KCTS was already running a for-profit store. It also opened a store at the Wolfchase Galleria in Memphis, Tennessee, though WKNO and SOK never reached an agreement; this was the first non-affiliated store in the chain. Other new markets added in 1996 and 1997 included Atlanta, Kansas City, Miami, Minneapolis (at the Mall of America), Pittsburgh, 1998 and 1999 brought new metropolitan areas including Phoenix and Tampa and Orlando, Florida. Between May 1997 and May 1998, the chain's headquarters moved within the Los Angeles area, from Carson to Cerritos.
In 1999, Learningsmith filed for bankruptcy and began liquidating its 87 stores. After contemplating acquiring as many as 64 leases, SOK acquired the leases of 21 units of Learningsmith for $920,000, (~$1.55 million in 2023) reopening the locations as Stores of Knowledge in January 2000. The Learningsmith leases acquired included locations in additional markets where the company did not have ties with the public television station, such as Nashville. In some cases, they expanded the chain's presence in existing markets; the Learningsmith store at MacArthur Center in Norfolk, Virginia, became a Store of Knowledge, joining another in Virginia Beach affiliated with WHRO-TV.
The chain also expressed interest in its final year in expanding its transportation offerings, such as model trains. It attempted to buy the 56-unit Great Train Store chain but failed to reach an accord before the company was liquidated. As a test, it set aside a quarter of the Orland Square Mall store in south suburban Chicago as a "Transportation Station" and considered expanding it into a separate chain of stores. CEO Jim Berk believed that consolidation in the space would leave mall vacancies and that landlords would be receptive to a new concept from an existing retailer.
In early 2001, the chain began to have cash flow issues after a poor holiday season and began "scrambling for capital", in Berk's words. The manager of the Store of Knowledge in Indianapolis, in association with WFYI, told the Indianapolis Business Journal that the first sign of trouble was when restocking orders were ignored. Additionally, a third attempt within a month to purchase the mall stores of the bankrupt Natural Wonders chain was rejected in March 2001, preventing Store of Knowledge from achieving critical mass in its store base. The failure to acquire the Natural Wonders stores led president and CEO Berk to defer his salary and the chain to defer $2 million in royalty payments to participating stations.
With the exception of KCET, which owned part of the chain itself and thus benefited financially from the opening of new stores everywhere in the United States, individual public television stations generally owned 15 to 25 percent of the store and received royalties or a one-percent cut of sales. A typical store grossed $2 million a year in sales. In exchange, stations provided promotional assistance. However, some early proceeds went toward expansion of the chain. Stores typically provided information and a telephone connection for prospective new members to the affiliated station.
Annual profits generally ranged from $18,000 to $100,000 a year for stations.
At the time the chain closed, 27 public television stations were associated with Store of Knowledge. The chain operated 91 stores, of which 12 had no affiliation with a public TV station in their area.
