Hey, if you ever want to find anything aired on network or cable news over the past 12 years, the Internet Archive has it (They've also recorded every other non-news program since then privately, not available for search)
Also, if you want to search text shown on screen since 2020 there's an AI vision search at https://api.gdeltproject.org/api/v2/summary/summary?d=iatvai and since 2017 at https://api.gdeltproject.org/api/v2/summary/summary?d=lts
You can also see what every news network is covering at the same time here https://api.gdeltproject.org/api/v2/summary/summary?d=ltb
