CRT

Cathode Ray Tube

CRT is the acronym for Cathode Ray Tube.

A type of vacuum tube used in older electronic devices, including televisions, computer monitors, oscilloscopes, and radar displays. The CRT works by firing a stream of electrons from an electron gun at a phosphorescent screen, causing it to emit light and create an image.

In a CRT, the electron gun is located at the rear of the tube, and a series of deflection coils around the neck of the tube control the path of the electron beam, scanning it across the screen in a pattern known as a raster. The colors of the image are created by combining different intensities of red, green, and blue phosphors on the screen.

CRTs were once the primary technology used in televisions and computer monitors, but they have largely been replaced by flat panel displays, such as LCD, LED, and OLED, which are thinner, lighter, and more energy-efficient. However, CRTs are still used in some specialized applications, such as medical imaging, and are valued for their high contrast, deep blacks, and lack of motion blur.

It all started as a book club.

Yes, I’m serious. I started my work on the web more than two decades ago. My first site was Helping Hand, which curated the best sites from around the web to help people with their computers and navigate resources on the Internet. Years later, I sold the domain to a company that helped folks quit smoking, one of my first big contracts.

I began blogging on Blogger and waxed poetic about everything from politics to Internet tools. I was all over the place and mostly wrote for myself – without much of an audience. I belonged to a Marketing Book club in Indianapolis that quickly grew out of control. Over time, I discovered that more and more of the group were coming to me for technology advice. The combination of my technology background and my business and marketing acumen was in high demand as the Internet rapidly changed the industry.

After reading Naked Conversations, I was motivated to better brand and control the content on the site. I also wanted more control over the look and feel of my blog, so I moved to my domain in 2006 and built my first WordPress site. Since I was focused on marketing technology, I didn’t want the domain with my name to get in the way, so I moved the site (painfully) to its new domain in 2008 where it’s grown ever since.

The Martech Zone is owned and operated by DK New Media, LLC, a company I started in 2009. After working with virtually every major online marketing department in my tenure at ExactTarget and launching Compendium, I knew there was a great demand for my expertise and guidance within such a complex industry.

DK New Media is my company overseeing my publications, podcasts, workshops, webinars, and speaking gigs. Highbridge is my agency with two other partners that help companies maximize their investment in sales, marketing, and related products. We offer integration, migration, training, strategic consulting, and custom development.

Thank you so much for your support over the years!
