3 terms

attribution technical

"Magellan AI has been a preferred attribution partner for iHeartMedia"

Attribution is the breakdown of why an investment or portfolio produced a given return by assigning portions of the gain or loss to causes such as overall market moves, industry exposure, or specific stock choices. It matters to investors because it acts like a post-game analysis or recipe check—showing which decisions added value, which hurt performance, and whether results reflect manager skill, luck, or broader market trends, guiding future decisions and risk assessment.

connected TV technical

"across podcasts, streaming audio, connected TV, and other digital media"

A connected TV is a television that can access the internet and run online apps, streaming services, and digital content directly on the screen, much like a giant tablet or computer. For investors, it matters because it represents a shift in how people consume media, opening new opportunities for advertising, content creation, and revenue growth in the entertainment industry.

simulcast data technical

"platform will leverage iHeartMedia's simulcast data, which maps listeners"

Simulcast data is a live feed of market information—prices, trades, and quotes—sent out to many users and platforms at the same time so everyone receives the same updates together. For investors this matters because equal, simultaneous access to pricing information helps ensure fairer trading, clearer price discovery, and reduced advantage for those who would otherwise get faster or exclusive updates; think of it like a stadium scoreboard that shows the same score to everyone at once.
