Sentry Broadcasting Corporation

1952-1963
The "Old Slab Serif 7", later used by Lasgahore Broadcasting and Television, was used by PRSE-TV as an alternate local symbol until the early 80s.

1963-1966
The logo, known as "The Locks", symbolized SBC's desire to become a network, rather than a mere local television station. This logo was made at the time the president was handing out the license to Galveston.

1966-1976
The logo was adopted when SBC got licenses for further cities. The logo depicted three bolts representing the ideology of the "three sentries", the founders of the newspaper, two of them were still alive by then, but oficially it represented the stations in Grand Rapids, Galveston and the federal capital Bensonland.

1976-1980
This logo was adopted in 1976 and was designed in-house by Peter Penelopez.

1986-1990
The spherical logo was dropped in 1986 in favor of a new design. Nicknamed as "The Double Screen", it won a competition that started in April 1985. Charles Martin, a university student, pitched the idea and was selected by in-house designer Peter Penelopez in the end of the year. The meaning of this logo was that the content - here as the simple SBC wordmark - would come out of the screen in order to reach a maximum amount of people.

1990-1994
On May 1st, 1990, the 1986 logo's colors were switched. The double screen became rainbow colored and the letters became silver.

1994-2000
SBC adopted a new logo consisting of three blue squares with the initials inside of them, similar to the then-future logo of the Nashlandian Broadcasting Service. Much of the graphical package was designed at Novocom, a rarity in the network's history.

2000-2005
The SBC cube was introduced at the stroke of midnight on January 1st, 2000.

2005-2008
The cube was simplified into a hexagon on August 1st, 2005, representing a dynamic future for the network.
