    The use of electronic medium in communication system is on geometric rise due to its flexibility, attractiveness, speed and efficiency. Various modes have been adapted in the transformation from the use of traditional billboards to electronic billboards in information dissemination. These modes include colour coated glass paper display, reflective mode display method, on-board editing of the content of an electronic billboards etc. with complicated problem of modifying the displayed content. This paper presents an implemented short message service (SMS) Controlled Electronic Billboard with Audio Output to enable ease and comfort of the administrator who determines the content of the billboard from any location. The input can be from a mobile phone or a web-based SMS application, provided the source is linked to a service provider. The billboard basically contains a microcontroller unit (AT89S52), a Subscriber Identity Module (SIM) modem and a matrix of Light Emitting Diodes (LEDs). The input to the display comprises a SIM900 Global System for Mobile communication (GSM) modem that takes care of the SMS and voice call reception for broadcasting any voice call placed on the SIM to the target audience. The text is received by the SIM modem and is transferred to the microcontroller which decodes the message using a set of rules. The decoded message is then used to automatically switch ON and OFF appropriate LEDs in order to display the character received as SMS on the screen of the billboard. Also, Voice call functionality has been incorporated to enable it receive calls and broadcast the audio message with a reasonable sound level to the target audience. It was designed, constructed, tested and found to meet the design specifications.

Some of the study’s prominent findings are: the most preferred social media platform for posting pictures by users is WhatsApp; the rationale is to inspire people, make people laugh, and express feelings or emotion. Findings also show that the most prevalent challenge users encounter while posting pictures on social media is poor network.
