Brisk Iced Tea, Purchase, N.Y., promoted a new video game on limited-edition 1-liter bottles sold in 7-Eleven stores in April and elsewhere in May and June. A Microsoft tag printed on bottles unlocks content in an Xbox game when consumers hold the bottle up to the Kinect sensor. In January, Brisk (a joint venture between PepsiCo and Unilever) participated in the 3-D theatrical release of “Star Wars: Episode I The Phantom Menace.”
