Electronic Message Centers (EMC)

“The literature from ISA comparing a common Las Vegas size sign at 1,500 square feet compared to a normal size sign in most cities at 150 square feet proved to help them better understand that their city would never be like Las Vegas.”

What is an Electronic Message Center (EMC)?

An electronic message center (EMC) is a sign that is capable of displaying words, symbols, figures or images that can be electronically changed by remote or automatic means.

These videos show examples of various EMC hold times (videos created and provided by Yesco Electronics).

This chart shows differences between EMCs and Billboards, providing a side-by-side comparison and contrast between on-premise and off-premise signs. Each type of sign has very distinct capabilities and purposes, each targets a specific audience and each has traditionally been treated under separate legal and regulatory regimes.
