Comcast Corporation
A media and technology company delivering broadband, wireless, video, and voice services under the Xfinity and Sky brands across the US, UK, and Italy, plus a content arm with NBC, Peacock, Universal Pictures, DreamWorks Animation, and theme parks like the new Epic Universe in Orlando. It began in 1963 when Ralph Roberts bought a small Mississippi cable operator, American Cable Systems; the name Comcast blends "communications" and "broadcasting." In 2026 it spun off its cable networks—USA Network, CNBC, and MSNBC—into independent Versant Media Group.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: -18.97M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
