Advent Corporation
Advent Corporation was a consumer audio and video hardware company founded in Cambridge, Massachusetts by Henry Kloss in 1967. It closed in 1981. The name came from the legal description ''the advent corporation (placeholder), advent corporation'' used in the incorporation (business), incorporation documents as a placeholder name before the actual name is selected. Around 1968, Kloss had quit KLH (company), KLH to develop a low-cost projection television, but had trouble financing the leading-edge research and development that was still required.

Advent Noise Reduction
Advent is a Christianity, Christian season of preparation for the Nativity of Christ at Christmas. It is the beginning of the liturgical year in Western Christianity. The name was adopted from Latin "coming; arrival", translating Koine Greek, Greek ''parousia''. In the New Testament, this is the term used for the Second Coming of Christ. Thus, the season of Advent in the Christian calendar anticipates the "coming of Christ" from three different perspectives: the physical nativity in Bethlehem, the reception of Christ in the heart of the believer, and the Eschatology, eschatological Second Coming. Practices associated with Advent include Advent calendars, lighting an Advent wreath, praying an Advent daily devotional, erecting a Christmas tree or a Chrismon tree, lighting a Christingle, as well as other ways of preparing for Christmas, such as setting up Christmas decorations, a custom that is sometimes done liturgically through a hanging of the greens ceremony.

Electronics Companies Established In 1967
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small elect ...
