In the early days of Hollywood, production logos and brands were simple and very much like their print counterparts, usually appearing on title cards and in the opening credits. The Paramount Pictures mountain logo hails from this era and originally featured no special effects. As the studios grew, more effort was put into their identities, and motion and sound began to be used. MGM and Universal were the first studios to take advantage of the new medium's possibilities, MGM first using Leo the Lion in 1924 and Universal debuting their globe around the same time. RKO Radio Pictures used their rotating globe and radio transmission tower with a Morse code-beeping soundtrack as early as 1929. In the 1930s, Twentieth Century Pictures introduced their futuristic "tower" logo, which had moving searchlights; it was carried over when they merged with Fox Film Corporation and became 20th Century-Fox. The first version of Columbia's mascot used a sparkler to represent her torch, and Universal's globes could rotate. The advent of television in the 1950s also opened the door to cel animation in production logos. Most studios had used cels for their animation departments' logos for some time by this point, but the demand for animation on TV, both as programming and for advertising, made more effects available for less money. TV itself started using logos on its programming: Desilu, Mark VII Productions and Revue Studios all had distinctive logotypes by the end of the decade, and Desilu's and Revue's were animated. By 1976, all of the major studios except Universal had switched their logos over to cel animation, and logos for smaller concerns and broadcasters were beginning to enter the computer age, using machines like Scanimate. With the 1980s came a return to the older style of logos. Warner Bros., one of the first studios to switch to a cel-animated abstract logo, brought back their WB shield logo as a matte painting in 1984. TV logos began switching from cels and 2D computer graphics to 3D computer graphics around the same time, and by the end of the decade, the quality of 3D animation had improved to the point that cinema quality was possible. Paramount had introduced a digital-looking logo in late 1986, but only the foreground animation in their logo was computerised. Universal's 1990 logo, introduced for its 75th anniversary, was pre-visualized with CG, but the actual logo was created using motion-control models. Throughout the 1990s, fully computer-generated logos increased in frequency. Disney was the last of the "Big Six" studios to re-design their logo with computer animation, debuting their logo with the release of in 2006. By 2007, almost all production logos have become produced on computers, and have reached a level of sophistication equivalent to that of the best special effects. There are some exceptions; the Mutant Enemy "grr, argh" ID was shot using a camcorder and paper models, and the producers of South Park even recycled footage from an old Braniff Airlines ad for their "vanity" logo. Producer Chuck Lorre uses his production card to post a long essay or observation in small type which changes each week and requires pausing with a recording device to read. Video games have taken on production logos as their capabilities have increased, and most modern game consoles have startup logos in their firmware. In addition, games themselves now feature startup logos of both the companies that produce the games as well as the ones who develop them. Video game startup logos also frequently feature the logos of game engines or other middleware used in the games. As with films, the production logos are also used in trailers and commercials for the video games. Many automobile manufacturers also use startup logos for their in car entertainment systems.
