There could also be updates about a host of hardware that Amazon makes -- smart displays, security cameras. and wireless headphones Echo Buds, among others. Amazon also offers a wide range of services, besides the retail operations. That include Prime Video service, Amazon Music, and the Audible audiobook service among other apps and websites.
