SeeSaw Networks announced that eight new members have joined its portfolio of place-based digital networks, giving advertisers access to an additional 3.5 impressions per week, via a total of 700 venues. Through a total of 40 affiliated digital networks, SeeSaw can now deliver about 50 million impressions weekly via 26,000 locations.

The newcomers are concentrated in retail venues, which include convenience stores, grocery stores, gas stations, etc., including: the BuzzHub Network, the TV Kart Network operated by Cabco; the Digital Promo Network; InStore Vision; QuickStore24 At Work Media Network, RDS Media, which serves wine and liquor stores; and World Narrowcasting Corp. Checkout and WNC Aisles, which both serve grocery stores.

TV Kart is a particularly interesting addition to the SeeSaw stable, delivering messages to digital displays on shopping carts installed and operated by Cabco Group. The carts were developed by the New Zealand-based company to entertain children during the shopping experience.

In addition to screens displaying content from sources like Nick Jr. and Hit Entertainment, the carts are modified with colorful plastic molding that makes them look like make-believe vehicles. Separate screens deliver advertising messages to shopping adults.

Separately, in October Cabco struck a deal with Premier Retail Networks to bring the carts to some of PRN's supermarket clients. The carts complement an array of in-store media controlled by PRN, including other place-based video screens and radio.

SeeSaw has been expanding aggressively in recent months. This week's partnerships come soon after the company's December addition of three new video networks reaching commuters, business professionals and tourists in New York's various transit systems. Altogether, the three networks cover more than 1,000 locations through the city, including taxis and high-traffic transit infrastructure.

Showcase Media Group gives SeeSaw's advertising clients access to interactive digital screens in the back seats of taxis. Affinity Ferry Network operates digital video displays in two ferry terminals. City 24/7 is installing 26-inch digital video touchscreen displays in disused phone booths, along with Verizon and landmark property owners, to deliver safety and consumer info.
