They're been working together for ten years already, but now American Greetings and Sesame Workshop have signed a new multi-year deal.
The long-term partnership includes licensing the Sesame Street trademark and characters in the US and Canada on greetings cards, party goods, gift packaging, ornaments, juvenile valentine's and sponsorship of Sesame Street on public TV (PBS Kids).
American Greetings is also sponsor of various multimedia educational outreach programs developed by Sesame Workshop.
Separately, the two have expanded the partnership internationally to include licensing agreements in Mexico, Australia and the UK.
"Our relationship with Sesame Workshop is one of outstanding collaboration in creating great product and respected working relationships within different departments of our organisations," said Michael Brown, VP of licensing at American Greetings.
"The reelationship has been beneficial to American Greetings as it has provided us the oppotunity to grow on many levels and recognise the reason why we do this everyday - for children and their parents/caregivers to celebrate special events while making the world a better place."
Maura Regan, Sesame Workshop's VP and general manager of global licensing, added: "We are proud to stand with American Greetings as we work together to make children's lives full of purpose, accomplishment, fun and joy. From developing quality products to supporting our educational programming, American Greetings' commitment to children creates a lasting impact."
