When a company starts to sell a new product, they often do a "product launch". That means that they try to let customers know about the new product and get them excited about it. "Product launches" can involve things like:

• sending emails to customers
• getting writers to write about the new product
• throwing a party to celebrate the new product's release

You can use "launch" either as a verb or as a noun:

We're launching it next week.

The launch is scheduled for mid-July.
