Which department does the speaker specifically thank?

I appreciate you all being here. This year, we exceeded our sales target for home electrical appliances. I’d like to thank our employees, especially the marketing and advertising departments, for a job well done. Because of their diligence and creativity, we have been able to expand our sales in many cities throughout the country, and now we are the top distributor of household machines. To show our gratitude and appreciation for your efforts, we’ve invited a band this evening to host a night of music and dance. So, dinner will be served right away, after which the band will take the stage.
