What Telecommunications History Group Inc does

The organization over time

Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.

Balance sheet

Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2017 to 2018, from $699k to $44k (−94%).

How it's funded, over time

Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.

Surplus & reserves

Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 8 reported years ran a deficit.

Leadership and staff

The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

Who funds it, year by year

2018 → 2023: the base broadened from 1 funder to 2 funders, grant income rose $5k → $53k.

4 of 10 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 10% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

From the IRS filings of Telecommunications History Group Inc’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.

How concentrated its funding is

Telecommunications History Group Inc leans on a few funders — its largest provides 87% of grant income and the top three 95%; half comes from just 1 funder.

Largest funder’s share by year: 2018 100% · 2019 100% · 2020 95% · 2021 98% · 2022 90% · 2023 100% — broadly stable.

“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.

How long its funders stay

20% of Telecommunications History Group Inc's funders are still giving 3 years after their first grant; 40% give in more than one year at all.

Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.

Where its funders are

Telecommunications History Group Inc draws 100% of its grant income from funders outside Colorado, across 5 states in all.

Funder states come from each funder’s own filing. $33k arriving through sponsors registered in 4 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
