Currently, other television station groups (such as Hearst Television) also implement common branding practices among its stations (even when affiliated with different networks). Some of the branding elements are now used by stations that are not O&Os or even affiliates of a certain network (such as Sunbeam Television's WHDH in Boston and WSVN in Miami using a variation of the circle 7 logo, and ABC affiliate KCRG-TV in Cedar Rapids, Iowa using CBS' "I Love Chicago" motif). Likewise, network affiliates may also license graphics packages for use on their newscasts and imaging from their networks to reduce the costs of licensing imaging from other parties; though it has been reduced in usage than in the past, many affiliate stations also license the network's imaging for their entertainment program and news promotions. Nonetheless, such practices and elements can still be traced back to the O&Os, which represented the earliest television station groups under common ownership, before the emergence and proliferation of national station ownership groups in the subsequent decades.
