Additionally, "Cats" was the first Broadway and West End show to capitalise on merchandising as a major revenue stream. Stalls were set up in the theatre lobbies to sell souvenirs ranging from toys and watches to coffee mugs, all of which were emblazoned with the cat's-eyes logo. The official "Cats" t-shirt became the second-best-selling t-shirt in the world in the 1980s, second only to the Hard Rock Cafe t-shirt. Merchandising has since become an important source of income for the industry.
