Well, maybe in the US. Here in the UK, we have Lorraine Kelly who has been presenting for just over 30 years now. She started as a reporter in 1984, and became a presenter in 1989. In 1993, when a new company took of production of the network morning show, Lorraine presented her own show at breakfast time a sort of 'KLG and Hoda' half hour, and later in '93 added anchoring the main show to her duties. In 1994, her show was extended to an hour, and she continued that show for 18 years. In 2012, she joined the main show (rebranded) as the host of the 7 - 8:30 portion (there was a newshour from 6-7), and continued her own show form 8:30 onwards. In 2014, the main show got rebranded again and Lorraine left to dedicate time to her own show. In addition to that, she's presented the mid-day show This Morning, similar to Today's Take I guess.
